Question

Solve the equation and check the solution.

a minus 2 and one-half = 1 and one-half

A: a = 1
B: a = 3 and one-half
c: a = 4
D: a = 4 and one-half

Answer 1

4

4 - 2.5 = 1.5.

Answer 2

C

Explanation:

You can write the equation like this:

A - 2.5 = 1.5

If you reverse the equation, it looks like this:

1.5 - 2.5 = A

1.5 - 2.5 = 4

A = 4
