Cross multiply
20(x+1)=14(x-1)
20x+20=14x-14
Subtract 14x on each side giving you
6x+20=-14
Subtract 20 on each side giving you
6x=-34
x=-34/6. Simplifying that you get x=-17/3. I hope this helps!!!

Answer:

X=-17/3

Step-by-step explanation:

x+1/x-1 = 14/20

20x+20=14x-14

Subtract 20 from both sides

20x+20-20=14x-14-20

Simplify

20x=14x-34

Subtract 14x from both sides

20x-14x=14x-34-14x

Simplify

6x=-34

Divide both sides by 6

6x/6=-34/6

Simplify

X=-17/3

Thank you for letting me help!!

Can anyone solve this for me
emmainna [20.7K]

Answer:

(-2, -4.5)

Step-by-step explanation:

We can solve this equation with substitution.

x=2y+7

3x-2y=3

We can "substitute" 2y+7 for x into the second equation:

3(2y+7)-2y=3

Distribute the 3

6y+21-2y=3

Add like terms

4y+21=3

Subtract 21 from both sides

4y=-18

Divide both sides by 4 to isolate y

y=-4.5

Plug -4.5 back in for y:

x=2(-4.5)+7

x=-9+7

x=-2

(x,y)=(-2,-4.5)
