Solve for r

4r-3=3 (3r+4)

-3

this is negative three because of math

Answer:r=-3

Step-by-step explanation:

multiply the 3 (3r+4) that gives you 9r+12 on that side

subtract 4r from the other side and from 9r and you are left with - 3=5r+12

subtract 12 from that side and from - 3 and you get - 15=5r

divide - 15 and 5r by 5 (here's how it looks - -) - 15/5 = 5r/5

you get - 3=r
