The value of given linear equation is 5.
Linear equation refers to a equation that has highest degree = 1 and can be expressed in the form 'ax + b'.
Given: 4 times x + 12 gives 8
To find: 2 times x + 7
With the help of the details given in the question, we get the linear equation: 4x + 12 = 8
=> 4x = 8 - 12
=> 4x = -4
=> x = -1
Now, 2x + 7 =?
For x = -1, 2 (-1) + 7 = -2 + 7 = 5
Thus, the value of given linear equation is 5.
