Hello!

You can put y into one of the equations

4x - 21 = -5x + 24

Add 5x to both sides

9x - 21 = 24

Add 21 to both sides

9x = 45

Divide both sides by 9

x = 5

You can now put x into one of the original equations

y = 4(5) - 21

y = 20 - 21

y = -1

The answer are x = 5 and y = -1

Hope this helps!
