Answer:
x=2 and y=2
Explanation:
3x+y=8;5x−3y=4
Step: Solve3x+y=8for y:
3x+y=8
3x+y+−3x=8+−3x(Add -3x to both sides)
y=−3x+8
Step: Substitute−3x+8foryin5x−3y=4:
5x−3y=4
5x−3(−3x+8)=4
14x−24=4(Simplify both sides of the equation)
14x−24+24=4+24(Add 24 to both sides)
14x=28
14x
14
=
28
14
(Divide both sides by 14)
x=2
Step: Substitute2forxiny=−3x+8:
y=−3x+8
y=(−3)(2)+8
y=2(Simplify both sides of the equation)
Answer:
x=2 and y=2
