Question

The sum of two numbers is –25. One number is 10 more than
the other one. Find the numbers.

Answer 1

A = -7.5 B = -17.5

Explanation:

A + B = -25

A = B + 10

Plug the second equation into the first equation:

B + 10 + B = -25

2B = -35

B = -17.5

Plug that value into the first equation:

A - 17.5 = -25

A = -7.5
