Question

Write 2 equations and solve for the numbers

Answer 1

y + x = 87

y = x + 35

x = 26

y = 61

Explanation:

y + x = 87

y = x + 35

substitute y with x + 35 in the first equation:

(x + 35) + x = 87

2x + 35 = 87

2x = 87 - 35

2x = 52

x = 52/2

x = 26

Find y by substituting x with 26:

y = (26) + 35

y = 61
