Question

Translate to a system of equations and solve.

The sum of two numbers is −7. Their difference is −59. Find the numbers.

How do I solve this step by step?

Answer 1

Two numbers (unknown yet): x and y

sum of them: x+y=-7

their difference x-y=-59.

So we have very simple linear system of two equations

x+y=-7
x-y=-59,

that, I think, you can solve easily.
