Question

two numbers have a sum of 37, and 4 times the first number minus the second number is equal to 43. what are the two numbers

Answer 1

x = 18

y = 29

Explanation:

x + y = 47

4x - y = 43

Substitution:

y = -x + 47

4x - (-x + 47) = 43

4x + x - 47 = 43

5x - 47 = 43

5x = 90

x = 18

18 + y = 47

y = 29
