Find the solution to the system of equations, x + 3y = 7 and 2x + 4y = 8. 1. Isolate x in the first equation: x = 7 − 3y 2. Substitute the value for x into the second equation: 2(7 − 3y) + 4y = 8 3. Solve for y: 14 − 6y + 4y = 8 14 − 2y = 8 −2y = −6 y = 3 4. Substitute y into either original equation: x = 7 − 3(3) 5. Write the solution as an ordered pair: ( , )
