The solution to the system of equation is (4, 2)
Solving by elimination
Given the system of equation below;
-x-y=-6
-7x-y=-30
Using the elimination method. Subtract both equations
-x +7x = -6 + 30
6x = 24
x = 4
Substitute x = 4 into equation 1 to have;
-4 - y = -6
-y = -6 + 4
-y = -2
y = 2
Hence the solution to the system of equation is (4, 2)
