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:
4. Substitute y into either original equation:
5. Write the solution as an ordered pair:
x = 7 β 3y
2(7 β 3y) + 4y = 8
14 β 6y + 4y = 8
14 β 2y = 8
β2y = β6
y = 3
x + 3(3) = 7
