Explanation:
#"distribute brackets on both sides of the equation"#
#-12p-15-6+28p=24+15p#
#rArr16p-21=24+15plarr" simplify left side"#
#"subtract 15p from both sides"#
#16p-15p-21=24cancel(+15p)cancel(-15p)#
#rArrp-21=24#
#"add 21 to both sides"#
#pcancel(-21)cancel(+21)=24+21#
#rArrp=45#
#color(blue)"As a check"# Substitute this value into the equation and if both sides are equal then it is the solution.
#-3(185)-2(-627)=-555+1254=699#
#3(233)=699#
#"both sides are equal " rArrx=45" is the solution"#
