Find the solution to the system of equations, x + 3y = 7 and 2x + 4y = 8.
1. isolate x in the first equation: x = 7 − 3y2.
substitute the value for x into the second equation: 2(7 − 3y) + 4y = 83.
solve for y: 14 − 6y + 4y = 814 − 2y = 8−2y = −6y = 34.
substitute y into either original equation: x =
7 − 3(3)5.
write the solution as an ordered pair: ( , )
