The value of x in the equation is 4.2.
<h3>How to calculate the value?</h3>
It should be noted that the equation given is:
12(-11x + 5) + 7 = 2 (x-9) - 451
This will be computed thus:
12(-11x + 5) + 7 = 2 (x-9) - 451
-132x + 60 + 7 = 2x - 28 - 451
Collect like terms
-132x - 2x = - 28 - 451 - 60 - 7
-130x = -546
Divide
x = 546/130
x = 4.2
The value of x in the equation is 4.2.
