Solve equations below:

45-z+89=

45-z+89=

-z = 89 - 45

z = - 44

To solve the equation 45 - z + 89 = 0, we will isolate the variable z by following these steps:

Step 1: Combine like terms on the left side of the equation.
45 - z + 89 = 0
134 - z = 0

Step 2: Move the constant term (134) to the right side of the equation by subtracting it from both sides.
- z = -134

Step 3: Multiply both sides of the equation by -1 to eliminate the negative sign in front of z.
-1 * (-z) = -1 * (-134)
z = 134

So, the solution to the equation 45 - z + 89 = 0 is z = 134.
