Answer:
<u>Part A</u>
One method for solving a system of equations is <u>solving by substitution</u>.
Substitute the variable in one equation with the expression of the variable in the other equation.
Replace the y of "y = 2x - 2" with "y = 4x" to make "4x = 2x - 2".
<u>Part B</u>
The only integer for which both equations give the same result is x = -1.
Therefore, the solution is x = -1
<h3><u>Part C</u></h3>
To solve the equation graphically, graph the lines y = 4x and y = 2x - 2.
The x-coordinate of the point of intersection is the solution to the equation 4x = 2x - 2
