Answer:
x=5 and y=22
Step-by-step explanation:
2x+3=13
2x+3+−3=13+−3(Add -3 to both sides)
2x=10
=
(Divide both sides by 2)
x = 5
Substitute5forxin4x−y=−2:
4x−y=−2
(4)(5)−y=−2
−y+20=−2(Simplify both sides of the equation)
−y+20+−20=−2+−20(Add -20 to both sides)
−y=−22
=
(Divide both sides by -1)
y=22
