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