1 answer:
Answer: Infinite solutions
Step-by-step explanation:
Solve4x+6y=9for x:
4x+6y=9
4x+6y+−6y=9+−6y(Add -6y to both sides)
4x=−6y+9
4x
/4
=
−6y+9
/4
(Divide both sides by 4)
x=
−3
/2
y+
9
/4
Substitute
−3
/2
y+
9
/4
for x in 12x+18y=27:
12x+18y=27
12(
−3
/2
y+
9
/4
)+18y=27
27=27(Simplify both sides of the equation)
27+−27=27+−27(Add -27 to both sides)
0=0
