To isolate the variable multiply both sides by 5.
-3 = x/5
-3*5 = x/5 * 5
-15 = x

Answer:
t= 52 seconds
A= 7,903 ft
Step-by-step explanation:
So start by writing each plane as an expression.
Plane A
3687+65.5*t is an expression for the ascent
Plane B
5000+40.25*t is an expression for the ascent
to find the time when they are at the same altitude set them equal to each other
3687+65.5*t = 5000+40.25*t
25.25*t = 1313
t= 52 seconds
to find the altitude solve one of the expressions with t=52
A =3687+65.5*52= 7093 ft
