Question

18x+8=8x+7 solve for x

Answer 1

x = -0.1

Explanation:

18x + 8 = 8x + 7

Take away 7 from both sides

18x + 1 = 8x

Take away 8x from both sides

10x + 1 = 0

Take away 1 from 0

10x = -1

Divide -1 by 10

x = -0.1

Answer 2

`x=-0.1`

Explanation:

To solve for x we must isolate the variable in order to find the value of the variable.


`18x+8=8x+7`
Subtract 8 on both sides:

`8-8=0`

`7-8=-1`
Subtract 8x on both sides:

`18x=8x-1`

`8x-8x=0`

`18x-8x=10x`

`10x=-1`
Divide both sides by 10:

`10x/10=x`

`-1/10=-0.1`

`x=-0.1`

Therefore your answer is -0.1.

I hope this helps.
