To find:
2x + y = 4 ..........(1)
x - y = 11 ...........(2)
Step by step solution:
We will use the substitution method to solve this problem:
We will take the value of y from second equation:
y = x - 11
We will put the above value in this equation:
2x + y = 4
2x + x - 11 = 4
3x = 15
x = 5
Putting this value in equation 2:
x - y = 11
y = x - 11
y = 5 - 11
y = -6
From here we can say that the value of x and y is 5 and -6 respectively.
