The calculated value of y in this linear system is 18
How to determine the value of y in this linear system?
From the question, we have the following parameters that can be used in our computation:
x + y + z = 62
x - y = 12
2x + y + z = 92
Subtracting the equations 1 and 2, we have
2x - x = 92 - 62
x = 30
In equation (2), we have
x - y = 12
This gives
y = x - 12
Substitute the known values into the equation
y = 30 - 12
Evaluate
y = 18
Hence, the value of y is 18
