Question

Math question, any help is appreciated <3

Answer 1

Since you already know the solution, you need to substitute every occurrence of x and y with those values: the first equation checks out, because it becomes

`3\cdot 4 - 2 \cdot 2 = 12-4 = 8`

The second becomes

`2 \cdot 4 + 3 \cdot 2 = Q \iff 8+6 = Q \iff Q = 14`
