$-np-80 < 60\qquad\text{change the signs}\\\\np+80$

------------------------------------------------------

$2a-5d=30\qquad\text{subtract 2a from both sides}\\\\-5d=-2a+30\qquad\text{change the signs}\\\\5d=2a-30\qquad\text{divide both sides by 5}\\\\d=0.4a-6$

Hi,
Let Sydney's age be x.

x+x-15=37
2x-15=37
2x=37+15
2x=52
x=52/2
x=26
Sydney is 26 years old.
