What's -128+138r=718 equal
german

Answer:

r = 6 3/23

Step-by-step explanation:

-128+138r=718

add 128 to each side

-128+128+138r=718+128

138r = 846

divide each side by 138

138r/138 = 846/138

r = 846/138

divide top and bottom by 2

r = 423/69

divide top and bottom by 3

r = 141/23

change this to a mixed number

r = 6 3/23
