Question 2. Solve 2x + 3y = 11 and 2x – 4y = – 24 and hence find the value of ‘m’ for which y =mx + 3.
Solution: 2x + 3y = 11 ... (1)
Subtract 3y both side we get
2x = 11 – 3y … (3)
Plug this value in equation second we get
2x – 4y = – 24 … (2)
11- 3y – 4y = - 24
7 y = - 24 – 11
-7y = - 35
y = - 35 / - 7
y = 5
Plug this value in equation (3) we get
2x = 11 – 3* 5
2x = 11- 15
2x = - 4
Divide by 2 we get
x = - 2
Plug the value of x and y in equation
Y =mx + 3.
5 = -2m +3
2 m = 3 – 5
M = - 2 / 2
M = - 1
Answer x = - 2 , 5 and m = -1
