Answer with Step-by-step explanation:
We have to determine the value of x on solving the system of linear equations:
2x-y = 11
x+3y = -5
2x-y=11
Adding y on both sides and subtracting by 11 on both sides, we get
y=2x-11
Putting value of y in x+3y = -5
x+3(2x-11) = -5
x+6x-33 = -5
7x -33 = -5
adding 33 on both sides, we get
7x= 28
Dividing by 7 on both sides, we get
x=4
Hence, Correct option is:
d. 4
