X - y = -2
4x - y = 4

ExplanationGiven the system of equations.

Use the elimination method as it is faster. We have to eliminate the y-term. (You can eliminate the x-term but it takes longer than eliminating y-term.)

Simply multiply the negative one in one of the equations.

We can finally eliminate the y-term by adding both equations.

Substitute the value of x in any given equations. I will substitute in the first equation.

Check the answer by substituting the value of x and y in both equations.

Second Equation

Hence, the solution is (2,4).
