Question

15x + 77y = 92,
55x - 33y = 22.​

Answer 1

Step-by-step explanation:

15x+77y=92 ------(1)

11 (5x-3y)=22

5x-3y=2---------(2)

multiplying equation 2 by 3,

15 x -9y = 6-------(3)

subtracting equation 3 from 1,

15x- 77y=92

-

15x -9y = 6

--------------------

-68 y= -86

y= -86/-68=43/34

substituting y=43/34,

5x-3y=2

5x-3×43/34=2

x=4.19
