Solve

First clean up both of the equations :

2.2x -3.1y = - 3.2

.9x +y = 8.8                <===== multiply by 3.1   then add to the top equation to get

 

2.79x + 3.1y = 27.28    <====Add to top equation

4.99 x = 24.08

x = 4.826                        <====== use this value of 'x' in either of the equations to calculate 'y'      You can finish.....
