Step 1: To Find

Since you have asked multiple questions, we will solve the first question for you. If you want any specific question to be solved then please specify the question number or post only that question.

We have to solve the system of equations by using elimination.

2x+2y=-2

3x-2y=12

Step 2: Calculation

Since we have a linear system of equations

2x+2y=-2

3x-2y=12

Add both the equations, we get

5x=10

x=2

When x = 2 then \(\displaystyle{4}+{2}{y}=−{2}\Rightarrow{2}{y}=-{2}-{4}\Rightarrow{y}=-{3}\).

Hence the solution of the system is (2,−3).
