Answer 1

Answer:

The answer is No solution

Step-by-step 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

$3=\frac{1}{3}\frac{}{} y\frac{+20}{3}$   Divide both sides by 3

x$=\frac{1}{9} y +\frac{20}{3}$

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

−18x+2y=−30

-18$(\frac{1}{9}y +\frac{20}{3} +2y=-30$)

−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
