The value of the variable of the u in the equation is u = 8.
Expression in mathematics is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
We are given that the expression as
10u+7=8(2u-4)-9
Now solving the bracket;
10u+7=16u-32-9
Combine the like terms;
10u+7=16u-41
6u=48 /6
u=8
