Question

Solve the equation: 3x - 7 = 20

Answer

Here’s how to solve the equation 3x - 7 = 20 step-by-step:

1. Isolate the x term:

Add 7 to both sides of the equation:

3x - 7 + 7 = 20 + 7
This simplifies to:

3x = 27

2. Solve for x:

Divide both sides of the equation by 3:

(3x) / 3 = 27 / 3
This gives you:

x = 9

Therefore, the solution to the equation 3x - 7 = 20 is x = 9.
