Solve the equations by finding the exact solution.
4 = x − 4
4= x - 4
+4 +4
8= x
4 = x − 4
Add 4 to both sides.
8 = x
To solve the equation 4 = x - 4, we need to isolate the variable x by performing algebraic operations.
First, we can start by adding 4 to both sides of the equation to eliminate the constant -4 on the right side:
4 + 4 = x - 4 + 4
This simplifies to:
8 = x
So, the exact solution to the equation is x = 8.
