Question

pls slove the 5 th sum​ do step by step

Answer 1

Answer:

given, 2x+3y=11......(1) x-2y=-12...... (2)

2x=11-3y

x=11-3y/2

now,

put the value of x in equ(2)

11-3y/2-2y = -12

11-3y-4y/2 = -12

11-7y/2 = -12

11-7y = -24

-7y = -24-11

-7y= -35

so, y= 35/7 = 5

and,

put the value of y in equ(1)

then,

2x+3y=11 (given)

therefore,

2x+3*5=11

2x = 11-15

2x=-4

x = -2

so, x=-2 and y=5

now, y=mx-4

y+4 = mx

so, m=y+4/x

m= 5+4/-2

m=-9/2 is right answer.
