#### Answer:

#### Explanation:

To solve this equation for

Start by adding

#5x + color(red)(cancel(color(black)(2y))) - color(red)(cancel(color(black)(2y))) = 15 - 2y#

#5x = 15 - 2y#

Now divide both sides of the equation by

#(color(red)(cancel(color(black)(5)))x)/color(red)(cancel(color(black)(5))) = (15 - 2y)/5#

#x = (15 - 2y)/5#

You can simplify this to get

#x = 15/5 - (2y)/5 = color(green)(3 - (2y)/5)#
