Solve the equation: 5x - 3 = 12.

Step: 1

Here’s an example of a linear equation with one variable: 5x - 3 = 12

In this equation, "x" is the variable. To solve for "x," to isolate it on one side of the equation.

First, let’s add 3 to both sides of the equation to eliminate the "-3" term: 5x - 3 + 3 = 12 + 3

This simplifies to: 5x = 15

Next, isolate "x" by dividing both sides of the equation by 5: \$(5x)/5 = (15)/5\$

This simplifies to: x = 3

Therefore, the solution to the linear equation is x = 3.

Explanation:

Here’s a linear equation in one variable. Add 3 to both sides to cancel out -3, then solve for x: x = 3.
