Answer:

2) -2/3

4) 17/5

Step-by-step explanation:

2)-4/3= 2g

-4=6g

g=-2/3

4) 9=5r - 8

-5r=-17

r=17/5

Answer:

g=-2/3, r=17/5, -15/14

Step-by-step explanation:

Multiply all terms by the same value to eliminate fraction denominators

2) -4/3=g/1/2

1/2(-4/3)= 1/2xg/1/2

Simplify

Multiply the numbers:

1/2(-4/3)=1/2xg/1/2

-2/3= 1/2xg/1/2

Cancel multiplied terms that are in the denominator

-2/3= 1/2xg/1/2 (cross out 1/2)

-2/3= g

Move the variable to the left

-2/3=g

g=-2/3

4)

Multiply the numbers

9/5=r-1x8.5

9/5=r-8/5

Add 8/5 to both sides of the equation

9/5=r-8/5

9/5+8/5=r-8/5+8/5

Add the numbers:

9/5+8/5=r-8/5+8/5

17/5=r

Move the variables to the left

17/5=r

r=17/5

6)

4/5z=-6/7

divide 4/5 5o each side

4/5zx5/4=-6/7x5/4

z=-30/28

(simplified= -15/14)
