Question

Solve for x: 3(x + 1) = -2(x - 1) + 6. (1 point)

a 1
b 4
c 5
d 25​

Answer 1

a) 1

Explanation:

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

3x + 3 = -2x + 2 + 6

3x + 3 = -2x + 8

Subtract 3 from both sides

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

3x = - 2x + 5

Add 2x to both sides

3x + 2x = -2x + 5 +2x

5x = 5

Divide both sides by 5

5x/5 = 5/5

x = 1
