Andre solved an equation, but when he checked his answer he saw his solution was incorrect. He knows he made a mistake, but he can’t find it. Where is Andre’s mistake and what is the solution to

the equation?

Original: 2(3x - 5) = 4(x + 3) + 8

Step 1: -6x + 10 = 4x + 12 + 8

Step 2: -6x + 10 = 4x + 20

Step 3: 10 = -2x + 20

Step 4: -10 = -2x

Step 5: 5 = x

• Step 2, x = 5

• Step 3, x = 15

• Step 1, x = 5

• Step 1, x = 15

• Step 2, x = 15
