Solve:
3x + 2y = -4
x - 2y = 4

We are given –

Here, we are going to solve this question using substitution method.

In the substitution method, we manipulate one of the equations such that one variable is defined in terms of the other. From Eq(2), we get –

Now, substitute (x = 4+ 2y) in Eq(1) for the y term found in the other equation.

Now, plug this value (y= -2) into Eq(2) to obtain a value for x.
