y = 4x
6x - 4y = 10
Use substitution method:
Substitute y = 4x into the 2nd equation:
6x - 4(4x) = 10
6x - 16x = 10
-10x = 10
-10x/-10 = 10/-10
x = -1
Substitute x = 1 into the 1st equation to solve for y:
y = 4x
y = 4(-1)
y = -4
Therefore, the solution to the systems of linear equation is:
(-1, -4) or x = -1, y = -4
