Question

Each student wrote a two-step equation. Peter wrote the equation 4x-2=10, and Andres wrote the equation 16x-8=40. The teacher looked at their equations and asked them to compare them. In what way are they SIMILAR?

Answer 1

Both variables (x) are 3.

4×3=12
12-2=10

16×3=48
48-8=40

3 fits the variable of the missing number.
