Question

QUICK!! HELP!!

Your friend says that 4x + 24x - 2 = 7(4x+2) X = 16..

What's your friends mistake??

Answer 1

4x + 24x - 2 = 7(4x + 2)

Distributive property.

4x + 24x - 2 = 28x + 14

Combine like terms.

28x - 2 = 28x + 14

Like terms cancel

-2 = 14

0 = 16

The equation is false and has no solutions.
