Step-by-step explanation:

2x+3y=11

2x-4y=24

Subtract equation 1 and 2

2x+3y=11

-2x+4y=-24 (multiplying -1 to equation 2)

7y=-13; y=-13/7

Substitute y in equation 1

2x+3y=11; 2x+3(-13/7)=11; 2x+(-39/7)=11;2x=11+39/7; 2x=77-39; 2x=38/7;

7

y=mx+3

-13/7=m(38/7)+3

-13/7-3=38m/7

-13-21 =38m/7

7

-34/7×7=38m

-34/38=m

m= -17/19
