Answer:(4,1)

Step-by-step explanation:

-x+3y=-1

X-2y= 2

______

Change second equation move all to right side to leave x on left side .

-x+3y= -1

X= 2y+2

Now substitute second equation that you made into first equation to find y.

-(2y+2)+3y= -1

-2y-2+3y=-1

Y-2=-1

Y= -1+2

Y= 1

Now substitute your answer of y into second equation you created to find x .

X= 2y+2

X= 2(1)+2

X=2+2

X=4

Softa [21]

We have

1/2 liter apple juice ---- 1/3 of her glass

1-liter apple juice --- x

x is the number of glass filled with 1 liter

$x=\frac{\frac{1}{3}}{\frac{1}{2}}=\frac{2}{3}$

we can obtain equivalent fractions like

$\frac{2}{3}=\frac{4}{6}$

How in the world do I answer this problem??

galben [10]

Answer:

Step-by-step explanation:

ST is y and SU is 2y-4.

Note that SU = ST + TU = y + 18

So we have 2y - 4 = y + 18

2y - 4 = y + 18

2y = y + 22

y = 22

So ST is 22.
