Pls help I WILL GIVE YOU BRAINLIEST! I NEED A EXPLANATION FOR THIS QUESTION

x = 3

y = 7

Step-by-step explanation:

y = 5x - 8  (I)

4x + 3y = 33 (II)

Substitute y = 5x - 8 in equation (II)

4x + 3 (5x - 8) = 33  

4x + 3*5x - 8*3 = 33

4x + 15x - 24 = 33           {Combine like terms}

      19x  - 24 = 33            {Add 24 to both sides}

            19x = 33 + 24

           19x = 57           {Divide both sides by 19}

             x = 57/19

x = 3

Substitute x = 3 in equation (I)

y = 5*3 - 8

y = 15 - 8

y = 7
