Answer:

Step-by-step explanation:

x + y = 169

y = x + 7

============

Substitute for y in the first equation

x + x+7 =169

2x + 7 = 169              Subtract 7 from both sides

2x+7-7 = 169 - 7

2x = 162                    Divide by 2

2x/2 = 162/2            

x = 81

=================

solve for y

y = x + 7

y = 81 + 7

y = 88
