Question

Use the method of subsititution to solve the system of linear equations.

-r + 10t = 22
-10r + 5t = 30

Answer 1

r=-2 t=2

Answer 2

from the first equation you get r = 10t-22
substitute this expression instead of r in the second equation giving you
-10(10t-22)+5t =30
solve for t. once you have t, r is 10t-22

Answer 3

solve for r and plug in second equation and then you will find t once you find t then plug in t's answer to original equation so you can find r
