Question

Solve −5x − 5 = −4x + 12 for x.

Answer 1

x = -17

Step-by-step explanation:

The equation is:

`\sf{-5x-5=-4x+12}`

First, add 4x on each side:

`\sf{-5x+4x-5=12}`

`\sf{-x-5=12}`

Add 5 to each side

`\sf{-x=12+5}`

`\sf{-x=17}`

`\sf{x=-17}`

Hence, x = -17.

Answer 2

x = -17

Step-by-step explanation:

-5x - 5 = -4x + 12 we want to isolate the variable so add 5x to both sides.

-5x + 5x - 5 = -4x + 5x + 12

-5 = x + 12 Subtract 12 from both sides

-5 - 12 = x

-17 = x
