Question

Solve the system, using substitution. Medal for correct steps, and for correct ordered pair, (a,b).

Answer 1

I don't want to type out in words what i am doing, but try to follow along with the math.

a + b = 4
2a + 3b = 11

a = -b + 4
2(-b + 4) + 3b = 11
-2b + 8 + 3b = 11
b = 3

a + (3) = 4
a = 1
