Question

Tom is 4 more than twice Andrews age. If Tom and Sara are twins, how old is Andrew?

Answer 1

The equation for Toms age is 2A + 4

The equation for Sara's age is 5A - 8

You would need to plug in numbers to find which number would give each problem the same result. The correct answer would be 4.

2(4)+4=12

5(4)-8=12

Good luck!
