2x-3y = -2 --------> (1)
4x + y = 24 -------> (2)

multiply equation number (1) by -2

-4x + 6y = +4

remove the x value from both equation (1) and (2) because its the same number and different sign

6y + y = 4 + 24

7y = 28

divide both by 7

y = 4

now putting y=4 in two equations

2x - 3y = -2
2x-3(4) = -2
2x-12 = -2
2x = -2 + 12
2x = 10
x = 5

or

4x + y = 24
4x + 4 = 24
4x = 24-4
4x = 20
x = 5

so its (5,4)
