Question

7x + 4 = 15x +36

Answer 1

Q : 7x + 4 = 15x + 36

first, move '+4' to the right side of the equation.
and you get:
7x = 15x + 36 - 4

second, move '15x' to the left side of the equation.
and you get:
7x - 15x = 36 - 4

third, do the subtraction.
and you get:
-8x = 32

forth, change the the left side of the equation to positive and the right side to negative.
and you get:
8x = -32

then, divide -32 by 8 so that you get 'x' equals to ___.
and you get:
x = -32/8
= -4 [the answer]

Answer 2

7x + 4 = 15x + 36

7x + 4 - 7x = 15x + 36 - 7x

4 = 8x + 36

4 - 36 = 8x + 36 - 36

- 32 = 8x

- 32/8 = 8x/8

- 4 = x

The answer is x = - 4

Insert the x value into the equation

- - - - - - - - - - - - - - - - - - - - - - -

Check

7x + 4 = 15x + 36

7(- 4) + 4 = 15(- 4) + 36

- 28 + 4 = - 60 + 36

- 24 = - 24

- - - - - - - s-

Answer 3

First, you need to get all of the variables on one side of the equation. But you have to make sure you do the same thing on both sides.

First, subtract 4 from both sides:
7x + 4 = 15x + 36
7x + 4 - 4 = 15x + 36 -4
7x = 15x + 32

Next: 7x - 15x = 15x + 32 - 15x
-8x = 32

From here, all you have to do is solve for x:
-8x / -8 = 32/-8
x = -4

Does this make sense?

Answer 4

combine like terms like 7x + 4 = 15x +36 move the 7x over to the 15x and subtract then you get 4 = 8x + 36 then move then 36 to the 4, you will have a negative number but that no biggy. you then get -32=8x. after that you divide the 8/8x to get x by itself and the divide the 8/-32 and your answer should be - 4

Answer 5

7X + 4 = 15X + 36
-15X + 7X = 36 - 4
-8X = 32
X= -4

Answer 6

Oh wow I have not done textbook Algebra in years:
7x + 4 = 15x + 36
7x + (4 - 36) = 15x
7x - 32 = 15x
-32 = 15x - 7x
-32 = 8x
(-32 / 8) = x
-4 = x

Answer 7

Since both sides are equal, what you do to one side must be done to the other.
7x + 4 = 15x +36
subtract 7x from both sides
4 = 8x + 36
subtract 36 from both sides
-32 = 8x
divide both sides by 8
-4 = x
x = -4

Answer 8

Like this:

7x + 4 = 15x +36 subtract 7x
4=8x+36 subtract 36
-32=8x divide by 8
x=-4

Answer 9

Get the x's on one side, and the numerical value on the other and then solve for x:

7x + 4 = 15x + 36

-32 = 8x

( I took 7x from BOTH sides of the equation in order to be left with the x term on one side only. I did the same thing with the numbers taking 36 from BOTH sides of the equation in order to end up with a numerical value on the other side. )

Next we solve for x by dividing BOTH sides of the equation to solve for x:

-32/8 = 8x/8, x = -4

Answer 10

7x + 4 = 15x + 36
7x - 15x + 36 -4
-8x = 32
x=-4
(you just move the things around)
