#x=-7#

Explanation:

#"collect terms in x on the left side and numeric values"#
#"on the right side"#

#"subtract "11x" from both sides"#

#12x-11x+5=-2#

#"subtract 5 from both sides"#

#x=-2-5=-7#

#color(blue)"As a check"#

Substitute this value into the equation and if both sides are equal then it is the solution.

#"left "=-84+5=-79#

#"right "=-77-2=-79#

#x=-7" is the solution"#
