The three solutions are (0, -2), (1, -4) and (3, -4)
Solution to equations
Given the equation below expressed as;
-8x - 4y = 8
This can also be expressed as;
-2x - y = 2
If the value of x is zero, then;
-2(0) - y = 2
-y =. 2
y = -2
Hence one of the solution is (0, -2)
If the value of x is 1, then;
-2(1) - y = 2
-2 - y = 2
y = -(2+2)
y = -4
Hence another of the solution is (1, -4)
If the value of x is 3, then;
-2(3) - y = 2
-6 -y = 2
-y = -2 + 6
y = -4
Hence another of the solution is (3, -4)
The three solutions are (0, -2), (1, -4) and (3, -4)
