Question

A system of equations is shown below.

y=4x
y=x-6
what is the x-value in the solution to the system?

Answer 1

Answer: x = -2

Explanation:

Since both equations are in the y-slope form,

we can use substitution for y in finding x.

Hence,

4x=x-6

4x-x=x-x-6

Subtract x from both sides to get x on one side and integer on one side.

`(3x)/(3) =(-6)/(3)`

Divide 3 to find the value of x

x=-2
