Answer:
The answer is x=3 and y=5
Step-by-step explanation:
Step: Solve 2x+y = 11 for y
2x+y=11
2x+y+−2x=11+−2x (Add -2x to both sides)
y=−2x+11
Step: Substitute −2x+11 for y in 4x−3y = −3
4x−3y = −3
4x−3(−2x+11) = −3
10x−33 = −3 (Simplify both sides of the equation)
10x−33+33 = −3+33 (Add 33 to both sides)
10x=30
=
(Divide both sides by 10)
x=3
Step: Substitute 3 for x in y = −2x+11
y=−2x+11
y=(−2)(3)+11
y=5 (Simplify both sides of the equation)
Answer:
x=3 and y=5
