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

Lol idk ask google. ejie

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.

This is the answer check it out
