8t + 5h = 220 5t + h = 112

what is the first step?

a. rewrite one of the equations for a variable: h=112-5t
b. substitute one equation in to the other: 8t+5(112-5t)
c. substitute one equation in to the other: 8(5t+h=112)+5h=220
d. rewrite one of the equations for a variable: 5h=220-8t

8t + 5h = 220

5t + h = 112
what is the first step?
