Question

solve the following simultaneous equation​

Answer 1

Step-by-step explanation:

1x+y=10_________(I)

3 3

1x+3y =10

3 3

3x+9y=30

2x+1y =11__________(ii)

4 4

4x+1y=11

4 4

16x+4y=44

from (I) we get

X=30-9y

3

by putting the value of x in (ii) we get

16(30-9y)+4y=44

3

420-9y+12y=44

3

420-3y=3x44

420-3y=132

-3y=-288

y=96

by putting the value of y in (I) we get

3x+9x96=30

3x=30-860

x=-296

i hope this will help you
