To solve these equations, we need to isolate the variable y.

1) (y+279) + 320 = 755
Combine like terms:
y + 599 = 755
Subtract 599 from both sides:
y = 156

2) (y+279) + 288 = 723
Combine like terms:
y + 567 = 723
Subtract 567 from both sides:
y = 156

So, the solutions to the equations are:
y = 156
