5x+3(4-x)=17?

Answer 1

5x+12-3x=17
2x=5
x=2/5

Now, putting the value of x
5*5/2 + 3{4- (5/2)} = 25/2 +3* { (8-5)/2}
=> 25/2 + 9/2
=>17 ans.
So, its the right equation

Answer 2

5x + 3(4 - x) = 17

5x + 12 - 3x = 17

2x = 17 - 12 = 5

x = 5/2

Answer 3

First step, multiply your way out of those brackets.

5x+3(4-x)= 17

becomes

5x+12-3x=17

Since you have 5x-3x which leaves 2x, you now have

2x+12=17

Take the 12 to the other side of the equation and you have to change its sign. This leaves

2x=17-12

and thus

2x=5

Since you can now divide each side of the equation by 2, you are left with

2x/2=5/2

Any number divided by itself leaves 1, that's the whole idea of dividing by 2 at this point. Thus as 2x/2=x and 5/2=2.5, we now see

x=2.5

and there you have your answer.

I hope this helps; please feel free to drop me a line if you want or need any more advice on this kind of thing.

Answer 4

5x + 12 - 3x = 17
2x = 5
x = 5 / 2

Answer 5

That is the correct answer
first you have to solve for x

5x+3(4-x)=17 (distribute)
5x+12-3x=17 (combine like terms)
2x+12=17 (subtract 12 from 17)
2x=5 (divide 5 by 2)
x=2.5

now plug the value for x (2.5) in the equation

5(2.5)+3(4-2.5)=17 (distribute)
12.5+3(1.5)=17 (distribute(multiplication)
12.5+4.5=17 (add)
17=17
so your answer was right

Answer 6

5x+12- 3x=17
2x= 17-12
x=5/2

Answer 7

5x+3(4-x) = 17
5x+12-3x = 17
5x-3x = 17-12
2x = 5
x = 5/2

Answer 8

5x+12-3x=17
2x=5
x=5/2

Answer 9

5x + 3(4 - x) = 17
5x + 12 - 3x = 17
5x - 3x = 17 -12
2x = 5
x = 5/2
x = 2.5

Answer 10

5x+12-3x=17
2x=17-12
2x=5
x=5/2
