Answer:
x= −3
/2 and y= 3
/2
Step-by-step explanation:
x= −3
/2 and y= 3
/2 because
3y=x+6
3y+−x=x+6+−x(Add -x to both sides)
−x+3y=6
−x+3y+−3y=6+−3y(Add -3y to both sides)
−x=−3y+6
−x
/−1 = −3y+6
/−1
(Divide both sides by -1)
x=3y−6
Step: Substitute3y−6forxin−x+y=3:
−x+y=3
−(3y−6)+y=3
−2y+6=3(Simplify both sides of the equation)
−2y+6+−6=3+−6(Add -6 to both sides)
−2y=−3
−2y/−2 = −3/−2
(Divide both sides by -2)
y=3
/2
Step: Substitute
3
2
foryinx=3y−6:
x=3y−6
x=3(
3
/2)−6
x = −3/2
(Simplify both sides of the equation)
Therefore the answer is
x= −3
/2 and y= 3
/2
I hope this helped you.
