Answer:
x=4 and y=2
Step-by-step explanation: Step 1: Solve x+3y=10 for x:
x+3y=10
x+3y+−3y=10+−3y(Add -3y to both sides)
x=−3y+10
Step 2: Substitute−3y+10for x in2x+2y=12:
2x+2y=12
2(−3y+10)+2y=12
−4y+20=12(Simplify both sides of the equation)
−4y+20+−20=12+−20(Add -20 to both sides)
−4y=−8
−4y
−4
=
−8
−4
(Divide both sides by -4)
y=2
Step 3: Substitute 2 for y in x=−3y+10:
x=−3y+10
x=(−3)(2)+10
x=4(Simplify both sides of the equation)
So your answer would be x=4 and y=2
