Question

solve 2x+3y=11 and 2x-4y= -24 and hence find the value of'm' for which y=mx+3​

Answer 1

Answer:

2x+3y=11 and 2x-4y=-24 also find value of m in eq y=mx +3

Step-by-step explanation:

now consider both as eq i and ii

2x+3y=11 -(i)

2x-4y=-24 - (ii)

now

by substitution method

from eq i

x=-3y+11/2 -(iii)

now put the value of x in eq ii

2(11-3y/2)-4y=-24

11-3y-4y=-24

11-7y=-24

-7y=-35

-y=-35/7

-y=-5

y=5

putting y value in eq iii

x=-3(5)+11/2

x=-15+11/2

x=-4/2

x=-2

now putting x and y value in eq iv

y = mx + 3

5=m(-2)+3

5-3 = -2m

2/-2=m

-1 =m

therefore value of x=-2 , y=5 , m = -1

Answer 2

Answer:

hey mate your answer is in attachment.....

Step-by-step explanation:

Further,

Substituting the value of x and y

• y = mx + 3
• 5 = -2m + 3
• 2m = 3-5
• m = -1

☑️ So here your value of m is (-1).

Hope it helps!✌️
