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 - 3y 2 (7 - 3y) + 4y = 8 14 - 6y + 4y = 8 14 - 2y = 8 - 2y = - 6 y = 3 x + 3 (3) = 7 (,)
