Question

1.(-3/5)x=-24

2.3x-(4-2x)=x-1



explain please thankkkssssssss

Answer 1

(-3/5)x=-24
x= (5x24)/3
= 120/3
= 40

3x-(4-2x)=x-1
3x - 4 + 2x = x-1
4x = 3
x= 3/4

Answer 2

(-3/5)x=-24
x = -24 * (-5 / 3) ==> Just do a cross-multiplication
x = +120 / 3 ==> Both negative signs cancel each other
x = +40 ==> Answer




3x-(4-2x)=x-1
3x - 4 + 2x = x - 1 ==> Multiply the members in paren by -1
3x - x +2x = +4 - 1 ==> put all unknowns to the left and constants to the right
4x = 3 ==> simplify the equation
x = 3/4 ==> answer

Answer 3

Hey there!

Here's the first answer.

(-3/5)x=-24 --> Write the problem.
x=40 Divide both sides of the equation by -3/5.

So the answer is x=40.

Here's the second answer.

3x-(4-2x)=x-1 --> Write the problem.
3x-4+2x=x-1 --> Distribute -1 into 4-2x.
3x+2x-4=x-1 --> Gather the x terms together and gather the constant terms together.
5x-4=x-1 --> Add 3x and 2x.
4x-4=-1 --> Subtract x on both sides of the equation.
4x=3 --> Add 4 to both sides of the equation.
x=3/4 Divide 4 on both sides of the equation.

So the answer is x=3/4.

Hope it helps!

Answer 4

1) (-3/5)x=-24
cut off the negative> (3/5)x=24
multiply both sides with 5/3 so that find x
(5/3)(3/5)x=24(5/3)
x=40=answer
2)3x-(4-2x)=x-1
multiply inside negative (4-2x
)3x-4+2x=x-1
group the x on the left side and number on the right side
3x+2x-x=-1+4
4x=3
x=3/4

Answer 5

1. multiply both sides by -5/3 to get x by itself
x = -40

2. distribute the negative
3x - 4 + 2x = x - 1
combine like terms
3x + 2x - x = 4 - 1
4x = 3
x = 3/4

Answer 6

for the 1st one the answer is x=40

multiply both sides by five which leaves u with -3x=-120
then divide both sides by 3 which leaves u with x=40

---

the 2nd problem is similar
multiply (4-2x) by negative 1. this leaves u with 3x-4+2x=x-1
subtract an x and add a 1.
this leaves u with 4x=3
which equals x=3/4

Answer 7

1) (-3/5)x = -24

You just need to multiply both sides by (-5/3).

(-5/3)(-3/5)x = (-5/3)(-24)
x = 40

2) 3x - (4 - 2x) = x - 1.

Start by eliminating the parentheses.

3x - 4 + 2x = x - 1

Then combine like terms on the left hand side.

5x - 4 = x - 1

Then subtract x from both sides and add 4 to both sides, combining like terms once again.

4x = 3

Finally, divide both sides by 4.

x = 3/4

Answer 8

1.
(-3/5)x = -24
(-5/3)*(-3/5)x = -24 * (-5/3)
x = 24 * (5/3)
x = 120/3
x = 40

2.
3x - (4 - 2x) = x - 1
3x - 4 + 2x = x - 1
5x - 4 = x - 1
5x - x = -1 + 4
4x = 3
x = 3/4

Answer 9

So length - width = 5 centimeters, so the size is comparable to 5 + width, or L = 5 + W the fringe equation is as follows: P = 2L + 2W we can replace in our equation for L and resolve for W sixty six = 2(5 + W) + 2W sixty six = 10 + 2W + 2W fifty six = 4W W = 14 Then we plug that returned into our unique equation to get L L = 5 + 14 = 19 centimeters

Answer 10

1.-3x/5=-24
-3x= -120[multiplying both sides by 3]
x= -120/-3=40
2.3x-(4-2x)=x-1
3x-4+2x=x-1
3x+2x-x= -1+4
4x=3
x=3/4

Answer 11

1. (-3/5)x=-24

multiply both sides by 5.....

-3x=-120

divide each side by -3.....

x=-120/-3=120/3=40

2. 3x-(4-2x)=x-1

remove brackets giving -4 and --2x, ie2x...

3x-4+2x=x-1

.....5x-4=x-1

subtract x from each side....

4x-4=-1

add 4 to each side....

4x= 4-1=3

divide each side by 4...

x=(3/4)
