Answer:

x = 6.67

Step-by-step explanation:

Rewrite the equation:

-4y = -3x +20

y = [tex]\frac{3}{4} x-5[/tex]

Find where y = 0

0 = [tex]\frac{3}{4} x -5[/tex]

5 = [tex]\frac{3}{4} x[/tex]

x = 6.67

Hope it helps! (:

3x-4y-8=12

first combine like terms

3x-4y=12+8

then isolate on variable

3x=20+4y

now divide by three to find x

x=20/3+4/3 x=8

to find y plug in x to the original equation

3(8)-4y-8=12

24-4y=20

-4y=20-24

-4y=-4

y=1
