Janet Greer · Answer 1

r=3

Step-by-step explanation:

16 - 2r = - 3r + 6r + 1

Combine like terms

16-2r = 3r + 1

Add 2r to each side

16-2r+2r = 3r+2r + 1

16 = 5r+1

Subtract 1 from each side

16-1 = 5r+1-1

15 = 5r

Divide by 5 on each side

15/5 = 5r/5

3 = r

Kaylah Mora · Answer 2

r=3

Step-by-step explanation:

Simplify the expression

16-2r=3r+1

isolate r by adding 2r to both sides

16=5r+1

isolate the numbers by subtracting 1 from both sides

15=5r

divide both sides by 5 to completely isolate r

r=3
