Answer:
g=-2/3, r=17/5, -15/14
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)
Your welcome ^^
