Question

What is the solution to the equation 4x = 42?
x = 6
x = 10
x = 10.5
x = 10.6

Answer 1

Your goal is to bring x alone. To do so, we have to preform the opposite of multiplication, which is utterly division. Divide 4 on both sides and see what you get as x.

Answer 2

\[4x=42\\ x=42/4\\ x=21/2\\ x=10.5 \]
