Solve the following system y=4x and 6x-4y=10

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
