Answer 1

The answer is No solution

Explanation:

Solve 3x+ -1/3y = 20 for x:

3x+ −1/3y+1/3y=20+1/3y(Add 1/3y to both sides)

3x=1/3y+20

`3=(1)/(3)\frac{}{} y(+20)/(3)` Divide both sides by 3

x
`=(1)/(9) y +(20)/(3)`

Substitute 1/9y+20/3 for x in−18x+2y=−30

−18x+2y=−30

-18
`((1)/(9)y +(20)/(3) +2y=-30`)

−120=−30 (Simplify both sides of the equation)

−120+120=−30+120 (Add 120 to both sides)

0=90

Answer 2

-15x + 5/3y = -10
5/3y = 15x - 10
y = 9x - 6
