Question

10r/8r + 3 - 2r - 3/ 8r + 3=?

Answer 1

10r/(8r + 3) - (2r - 3)/ (8r + 3)=?               same LCD  so just subtract the top & repeat the bottom  (the Minus sign will get distributed to the term)

10r - (2r-3)/(8r+3)  distribute the negative sign to bracket

10r - 2r+3/(8r+3)  combine like terms

(8r+3)/(8r+3)        simplify
