Question

question no. 2 .....​

Answer 1

First step

2x+3y-2x+4y= 11 + 24

7y = 35

y = 5

Second step

2x + 15 = 11

2x = 11-15

x = -4/2

= -2

To verify the value

2x - 20 = -24

2x = -24+20

x= -4/2

= -2

Third Step

( Find the value of m )

y = mx + 3

5 = m×(-2)+3

5-3=-2m

2 = -2m

2/-2 = m

-1 = m
