Question

the summ of a certain number and a second number is -42. the first number minus the second is 52. Find the two numbers. HOW DO I SOLVE QUESTIONS LIKE THIS?? AND WHATS THE ANSWER?????

Answer 1

a + b = -42
a - b = 52

add the two equations: a + b + a - b = -42 + 52

so 2a = 10

so a = 5

Answer 2

x + y = -42

x - y = 52

x = 5
y = -47

Answer 3

Sorry I kind of skipped some steps, but if you do the algebra, you should be about to get it.

Answer 4

therefore b = -47
