Answer:
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
Divide both sides by 3
x

Substitute 1/9y+20/3 for x in−18x+2y=−30
−18x+2y=−30
-18
)
−120=−30 (Simplify both sides of the equation)
−120+120=−30+120 (Add 120 to both sides)
0=90
