Question

8x+12y=48,9x+12y=42 by elimination method​

Answer 1

Step-by-step explanation:

subtract both the equations to eliminate y

8x+12y=48...........(1)

9x+12y=42...........(2)

- - -

__________

-x+0=6

x= -6

now put the value of x in eq(1)

8(-6)+12y=48

12y=48+48

y=96/12

y=8

so answer is (x= -6) & (y= 8)

Answer 2

Answer:

The answer will be:
