Question

What is this? Solve for x: 3(x + 1) = −2(x − 1) + 6.

Answer 1

`x=1`

Explanation:

STEP 1: Simplify 3(x+1).

`3x+3=-2(x-1)+6`

STEP 2: Simplify −2(x−1)+6.

`3x+3=-2x+8`

STEP 3: Move all terms containing x to the left side of the equation.

`5x+3=8`

STEP 4: Move all terms not containing x to the right side of the equation.

`5x=5`

STEP 5: Divide each term by 5 and simplify.

`x=1`
