2x+4y=7 and 4=5-7x identify the solution
4 = 5 - 7x 7x = 5 - 4 7x = 1 x = 1/7; 2(1/7) + 4y = 7 4y = 7 - 2/7 = 49/7 - 2/7 = 47/7 y = 47/28 The solution for the system 2x+4y=7 and 4=5-7x is (1/7, 47/28)

4 = 5 - 7x
7x = 5 - 4
7x = 1
x = 1/7;
2(1/7) + 4y = 7
4y = 7 - 2/7 = 49/7 - 2/7 = 47/7
y = 47/28
The solution for the system 2x+4y=7 and 4=5-7x is (1/7, 47/28)
