Answer:

Graphical approach

Explanation:

The other answers are the most efficiant means of solving this question, but i just wanted to provide a graphical interpritation:

enter image source here

Red #=> y = x +5 #
Blue #=> y= 2 #

Where these two lines intersect, that is the solution to the problem:

Hence we see they cross at #(-3,2)#

#=> x= -3 #

Im not sure if you learnt about grpahs of lines, but when you do, this is an interesting way of thinking about it!
