Solve for x and y:

 

2x - 3y = -3.2 - 0.2x + 0.1y

x  = 0.6x - y + 8.8 - 0.5*x

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.....
