- 2a+b=-14 2a-2b=-16

a=5, b=-24

This is a system of linear equations which can be solved by adding or subtracting equations to eliminate one variable. We could add both equations to make b be eliminated. The resulting equation would be 4a = -30, by dividing both sides by 4 we get a = -30/4 = -7.5. Now, using the value of a in the first equation (2*-7.5 + b = -14), we can find b = -14 - (2*-7.5) = -24. Therefore, a equals to -7.5 and b equals to -24 .
