Answer:

#x=11#

Explanation:

The first step is to distribute the bracket on the left side.

#rArr12x+240=372#

Isolate 12x by subtracting 240 from both sides.

#12xcancel(+240)cancel(-240)=372-240#

#rArr12x=132#

divide both sides by 12

#(cancel(12) x)/cancel(12)=132/12#

#rArrx=11#

Substitute this value into the left side of the equation and if it equals the right side then it is the solution.

#rArrx=11" is the solution"#
