by multiplying eq 1×3
we get
2x+3y=11
2x=11−3y
Substituting this in 2nd equation, we get
(11−3y)−4y=−24
11−7y=−24
7y=11+24
y=
7
35
=5
Substituting value of y
2x=11−3×5
x=
2
−4
=−2
Now, to find the value of m, we substitute the values of x and y in the equation
5=m×(−2)+3
m=
−2
5−3
=−1

Answer:
2x - y = -1
+2x +3y=11
4x +2 y = 10
4x+y = 10/2
x+y= 5-4
x+y = 1
or use this formula and put ur values instead of this values
