What is the solution to -1/4(4/9-3x)-2/9=7/9

liq [111]

Answer:

40/27

Step-by-step explanation:

-1/4(4/9-3x)-2/9=7/9

-1/9+3/4x=7/9+2/9

3/4x=9/9-(-1/9)

3/4x=9/9+1/9

3/4x=10/9

x=(10/9)/(3/4)

x=(10/9)(4/3)

x=40/27

How to solve system graphically 4y = x + 8, x = 2/3y +2

8_murik_8 [283]

4y = x + 8
x = 2/3y + 2
4y = x + 8
2/3y = x + 2
3 1/3y = 8 
3 1/3 3 1/3
 y = 2 2/5
4(2 2/5) = x + 8
 9 3/5 = x + 8
 -8 -8
 1 3/5 = x
 (x y) = (1 3/5, 3)
