Question

Solve the following system of equations by elimination. What is the value of y?
2x-5y=1
-3x+2y=-18

please help!

Answer 1

Answer:

y = 3

Step-by-step explanation:

2x - 5y = 1  ----------------(i)

-3x + 2y = -18 ---------------(ii)

(i) * 3               6x - 15y = 3

(ii)*2             -6x + 4y = -36

add==>                  -11y = -33

                                  y = -33/-11

                                  y = 3
