Answer:

x = 33 + 11y

Step-by-step explanation:

12x + 13y = 36

13x + 2y = 69

One of the needs to change so that an x or y is the subject of the equation.

36 - 12x = 13y

13x + 2y + 36 - 12x = 69 + 13y

x + 2y + 36 = 69 + 13y

x + 2y + 36 - 36 = 69 + 13y - 36

x + 2y = 13y + 33

x + 2y - 13y = 13y - 13y + 33

x - 11y = 33
