Question

Solve 2x + 3y = 11 and 2x – 4y= - 24 and hence find the value of m for which

y = mx + c.​

Answer 1

Answer:

2x+3y=11. equ. no.1

2x-4y=-24. equ. no.2

upon

minus Karne par,

-y=-13,

y=13

now,put the value of y in equ. no.1

2x+3*13=11

2x=11-39

2x=-26

X=-26/2

X=-13

now, y=mx+c

-13=m*13

m=-13/13

hence, m=-1
