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) 3x - 9y = 33

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
