Where could you put the 52? Guess if you are not 100% sure.

aaronandyson · Answer

x = 2y - 6

52 = 2y-6

aaronandyson · Answer

Taking 
52 = 2y - 6

We add 6 on both sides

52+6 = 26 + 6 -6

The two 6 on the right hand side cancel out to become 0

58 = 2y

Divide both sides by 2

58/2 = 2y/2

29 = y

aaronandyson · Answer

y = 29

x = 2y-6

x = 2(29) - 6

x = 58 - 6

x = 52
