Answer:
x = -1
Explanation:
Let's solve your equation step-by-step.
7x + 12 = 2(1 − x) − x
Step 1: Simplify both sides of the equation.
7x + 12 = 2(1 − x) − x
7x + 12 = (2) (1) + (2) (− x) + − x (Distribute)
7x + 12 = 2 + − 2x + − x
7x + 12 = (− 2x + − x) + (2) (Combine Like Terms)
7x + 12 = − 3x + 2
7x + 12 = − 3x + 2
Step 2: Add 3x to both sides.
7x + 12 + 3x = − 3x + 2 + 3x
10x + 12 = 2
Step 3: Subtract 12 from both sides.
10x + 12 − 12 = 2 − 12
10x = − 10
Step 4: Divide both sides by 10.
10x/10 = - 10/10
x = - 1
Hope this helps! Sorry if it is confusing!
