Answer:
r=-3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4r−3=3(3r+4)
4r+−3=(3)(3r)+(3)(4)(Distribute)
4r+−3=9r+12
4r−3=9r+12
Step 2: Subtract 9r from both sides.
4r−3−9r=9r+12−9r
−5r−3=12
Step 3: Add 3 to both sides.
−5r−3+3=12+3
−5r=15
Step 4: Divide both sides by -5.
−5r
−5
=
15
−5
