Step-by-Step Solution

Step 1: Eliminate the constant on the left side

Start by removing the $-7$ from the left side. To do this, add 7 to both sides of the equation:
$$
4x - 7 + 7 = 89 + 7
$$
Simplifying both sides gives:
$$
4x = 96
$$

Step 2: Solve for $ x $

Now, divide both sides by 4 to isolate $ x $:
$$
rac{4x}{4} = rac{96}{4}
$$
This simplifies to:
$$
x = 24
$$
