Find the solution to the system of equations. 4x + 3y = –1 3x – 9y = 33
alexandr1967 [171]

Answer:

Step-by-step explanation:

4x + 3y = -1         --------------(i)

3x - 9y = 33        -------------(ii)

multiply equation (i) by 3

(i)* 3     12x + 9y = -3

(ii)       <u>   3x - 9y = 33</u>

add,       15x = 30

                 x = 30/15

                 x = 2

Put x =2 in Equation (i)

4*2 + 3y = -1

8 +3y = -1

     3y = -1-8

     3y = -9

       y = -9/3

       y= -3
