Answer:

#x=-4#

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"#
