german3 years ago
5 0

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

jeyben [28]

Answer:

x= 13/22

Step-by-step explanation:

you can substitute y= 34 x on the second equation

34x = -54x +52  add 54x to both sides

34x +54x  = -54x +54x +52

88x = 52  divide both side by 4

22x = 13  divide both sides by 22

x= 13/22
