Question

How do you solve `2x+7=-7+x+6-x`?

Answer 1

`x = -4`

Explanation:

`2x + 7 = -7 + x + 6 - x`

Combine like terms on the right hand side of the equation:
`2x + 7 = -1`

Subtract `color(blue)7` from both sides:
`2x + 7 quadcolor(blue)(-quad7) = -1 quadcolor(blue)(-quad7)`

`2x = -8`

Divide both sides by `color(blue)2`:
`(2x)/color(blue)2 = (-8)/color(blue)2`

Therefore,
`x = -4`

Hope this helps!

Answer 2

`x=-4`

Explanation:

It's a simple addition and subtraction problem all you have to do is to get the numbers on a side and terms containing `x` on the other side

`2x+7=-7+x+6-x`

`2x+7=-7+6cancel(+x-x)`

`2x+7=-1`

Subtract `7` from both sides

`2xcancel(+7-7)=-1-7`

`2x=-8`

Divide both sides by `2`

`x=-4`
