Step-by-step explanation:
1.I will solve your system by substitution.
−x+2y=6;6y=x+18
Step: Solve−x+2y=6for x:
−x+2y+−2y=6+−2y(Add -2y to both sides)
−x=−2y+6
[tex]\frac{-x}{-1} =\frac{-2y}{-1}[/tex] Divide by -1
x=2y−6\
Well I did this problem differently I substitute
Step: Substitute2y−6for x in6y=x+18:
6y=x+18
6y=2y−6+18
6y=2y+12
6y+−2y=2y+12+−2y
4y=12
[tex]\frac{4y}{4} =\frac{12}{4}[/tex]
y=3
Step: Substitute3 for y in x=2y−6:
x=2y−6
x=(2)(3)−6
x=0
Your final answer will be x=0 and y=3
