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