What is the solution to the equation 3 = x + 3 - 5x?

Back

x = 0.

Front

What is the first step to solve the equation -3(1 + 6x) = 14 - x?

Back

Distribute -3 on the left side: -3 - 18x = 14 - x.

Front

How do you combine like terms in the equation -3 - 18x = 14 - x?

Back

Add 18x to both sides and add 3 to both sides: 0 = 17 + 17x.
