Find the solution to the system of equations: x + 3y = 7
and 2x + 4y = 8
1. isolate x in the first equation:
2. substitute the value for x into the second equation:
3. solve for y:
x = 7 - 3y
27 – 3y) + 4y = 8
14 - 6y + 4y = 8
14 – 2y = 8
-2y =-6
y = 3
x+3(3) = 7
4. substitute y into either original equation:
5. write the solution as an ordered pair:
