-29 = -4 + 5u
-29 = -4 + 5u
-29 + 4 = 5u
-25 = 5u
-5 = u
To solve the equation "-29 = -4 + 5u", we need to isolate the variable "u" by performing necessary operations on both sides of the equation.
Here's how we can do it step by step:
1. Start with the given equation: -29 = -4 + 5u
2. We can simplify the equation by adding 4 to both sides to eliminate the -4 term on the right side:
-29 + 4 = -4 + 5u + 4
-25 = 5u
3. Next, we divide both sides of the equation by 5 to isolate the variable "u":
-25/5 = 5u/5
-5 = u
So, the solution to the equation is u = -5.
