Explanation:
#"distribute bracket on the left side of equation"#
#12x-2-23=-61#
#rArr12x-25=-61larrcolor(blue)"simplifying"#
#"add 25 to both sides"#
#12xcancel(-25)cancel(+25)=-61+25#
#rArr12x=-36#
#"divide both sides by "12#
#(cancel(12) x)/cancel(12)=(-36)/12#
#rArrx=-3#
#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"#
#2(-18-1)-23=-38-23=-61=" right side"#
#rArrx=-3" is the solution"#
