Answer:

1a) 90 = 2y + 2(2x)        1b) 45 - 2x = y          

Step-by-step explanation:

1a) 90 = 2y + 2(2x)        

 

1b) 90 = 2y + 2(2x)           Use the equation from above and multiply

90 = 2y + 4x

-4x          - 4x               Subtract 4x from both sides

90 - 4x = 2y                 Divide both sides by 2

45 - 2x = y
