Step-by-step explanation:

−5x−9y=3+5x−9y=−2

Consider the first equation. Subtract 5x from both sides.

−5x−9y−5x=3−9y

Combine -5xand -5x to get -10x

−10x−9y=3−9y

Add 9y to both sides.

−10x−9y+9y=3

Combine -9y and 9y to get 0

−10x=3

Divide both sides by -10

x=− 3/10

Consider the second equation. Insert the known values of variables into the equation.

3+5(− 3/10)-9y = -2

after solving a lot you'll get. y=7/10

so x=3/10

y= 7/10
