7x-3y+5=16 and 4y=3x+17
Solve the system of equations and enter the solution as an ordered pair.
Equation 1:
7x-3y+5=16
7x - 3y = 11
Equation 2:
4y=3x+17
-3x + 4y = 17
Eliminate the y terms; multiply equation 1 by 4, multiply
equation 2 by 3, then add the two resulting equations.
4 * (7x - 3y) = 4 * 11 28x - 12y = 44
3 * (-3x + 4y) = 3 * 17 -9x + 12y = 51
-----------------------
Add ---> 19x = 95
19x = 95
x = 5
Substitute that into the second equation and solve for y.
4y = 3*5 + 17
4y = 15 + 17
4y = 32
y = 8
The answer is (5,8)
