Apply distributive property: Apply the distributive property to the right side of the equation.4r−3=3(3r+4)=3×3r+3×4=9r+12
Expand the right side: Rewrite the equation with the expanded right side.4r−3=9r+12
Rearrange terms: Get all terms with r on one side and constant terms on the other side by subtracting 9r from both sides.4r−9r−3=9r−9r+12−5r−3=12
Isolate the term with : Isolate the term with by adding to both sides of the equation.\newline−5-5−5r - 333 + 333 = 121212 + 333\newline−5-5−5r = 151515
Solve for r: Solve for r by dividing both sides by \(-5").\newline−5r/−5=15/−5-5r / -5 = 15 / -5−5r/−5=15/−5\newliner=−3r = -3r=−3
