Question

Solve 3x+4y = and 4x-2y =13 ,the value of m for which y=mx+3.​

Answer 1

hey mate u not mention a numerical after 3x+4y=?

so,I conclude it as '7'

3x+4y=7-1st eq

4x-2y=13-2nd eq

multiply 2nd eq with '2'

3x+4y=7

8x-4y=26

+4y,-4y get cancel

3x+8x=33

11x=33

x=3,4y=7-3x=7-9=-2

y=-2/4=-1/2

y=mx+3

-1/2=3m+3

-1=6m+6

-1=6(m+1)

m+1=-1/6

m=-1/6-1

m=-7/6
