Plug in 3 for "y":
7x + 2y = 48
7x + 2(3) = 48
2*3 = 6
7x + 6 = 48
Then, you have to subtract 6 to both sides..
7x = 42
Divide 7 to both sides and the your answer would be 6
7x + 2y = 48
7x + 2(3) = 48
2*3 = 6
7x + 6 = 48
Then, you have to subtract 6 to both sides..
7x = 42
Divide 7 to both sides and the your answer would be 6
