Explanation:
#"distribute the brackets on the left side of the equation"#
#32-4p-7+p=22#
#rArr-3p+25=22#
#"subtract 25 from both sides"#
#-3pcancel(+25)cancel(-25)=22-25#
#rArr-3p=-3#
#"divide both sides by "-3#
#(cancel(-3) p)/cancel(-3)=(-3)/(-3)#
#rArrp=1#
#color(blue)"As a check"# Substitute this value into the left side of the equation and if equal to the right side then it is the solution.
#4(7)-(6)=28-6=22=" right side"#
#rArrp=1" is the solution"#
