Using the substitution method, solve for x and y below, showing your work every step of the way.
If 2x + 2y = 20
&
5x - 3y = 15
Hallo guest
2x+2y=205x−3y=15Using the first equation.2x=20−2yx=10−ynow we plug that value of x into the second equation5(10−y)−3y=1550−5y−3y=15−8y=−35y=358x=10−y=10−358x=458
