Explanation:
#"divide both sides by "-5#
#cancel(-5)/cancel(-5)(2x-4)=60/(-5)#
#2x-4=-12#
#"add 4 to both sides"#
#2xcancel(-4)cancel(+4)=-12+4#
#2x=-8#
#"divide both sides by 2"#
#x=(-8)/2=-4#
#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.
#-5(-8-4)=-5xx-12=60#
#x=-4" is the solution"#
