Solve the following using the substitution method and find the value of x and y:
2x + 4y = 16
5x – 3y = -25

The correct answer is: -2, 5

Given equations;
2x + 4y = 16
5x – 3y = -25
substitution method;
substitute every option in both equations
which satisfies both equations that's is our answer.
Here, the numbers -2,5 satisfies both equation.
2(-2) + 4(5) = 16
5(-2) – 3(5) = -25
So, that the value of x=-2 and y=5
