To solve this problem using the equation 36x - 19 = 53, we can follow a two-step method. Here's how we can proceed:
Step 1: Isolate the variable term.
Add 19 to both sides of the equation:
36x - 19 + 19 = 53 + 19
This simplifies to:
36x = 72
Step 2: Solve for the variable.
Divide both sides of the equation by 36:
36x/36 = 72/36
This simplifies to:
x = 2
