If you know the answer to this, equation please aswell, thank you!

Answer:
<S = 72 degrees
Step-by-step explanation:
Your first step you need to do is find what x is.
As the lines on the shape shows, angle S is congruent to angle Q so you would have to write the expression 4x + 12 = 5x - 3.
Try to get rid of the smaller coefficient which is 4x. So subtract 4x - 4x and 5x - 5x. This would leave you with 12 = x - 3. (Remember 1x = x)
Try to get the variable alone so add 3 to the constants, so -3 + 3 and 12 + 3 which leaves you with 15 = x.
Now all you need to do is replace the x in the angle S expression.
4(15) + 12 = ?
4 * 15 = 60
Then 60 + 12 = 72 degrees.
If you want to check your answer, remember that angle S is equal to angle Q, which you can do as 5(15) - 3 which also equals 72 degrees.
