Question

What's the answer for 4r-5=7-3r+3(2-r)

Answer 1

9/5 or 1.8

Explanation:

4r - 5 = 7 - 3r +3(2 - r)

Distribute 3 on the right side.

4r - 5 = 7 - 3r + 6 - 3r

Combine like terms on the right side.

4r - 5 = -6r + 13

Add 6r to both sides. Add 5 to both sides.

10r = 18

Divide both sides by 10.

r = 18/10

r = 9/5 = 1.8
