Step-by-Step Guide to Solve y = 2x + 3

Solving the equation y = 2x + 3 involves understanding its components and applying basic algebraic principles. Follow these steps to solve it efficiently:

Step 1: Identify the Equation Type

The equation y = 2x + 3 is a linear equation in the slope-intercept form, y = mx + b, where:

• m is the slope (2 in this case)


• b is the y-intercept (3 in this case)

Recognizing this form is crucial for solving the equation. (slope-intercept form, linear equation)

Step 2: Isolate the Variable

To solve for x or y, isolate the variable on one side of the equation. For example, to solve for x when y is given:

1. Subtract 3 from both sides: y - 3 = 2x


2. Divide both sides by 2: x = (y - 3) / 2

📌 Note: Always perform the same operation on both sides to keep the equation balanced. (isolating variables, algebraic operations)

Step 3: Plug in Values (If Needed)

If you have a specific value for y, substitute it into the equation to find x. For instance, if y = 7:

x = (7 - 3) / 2 = 4 / 2 = 2

This process works similarly if you’re solving for y given a value for x. (substitution method, solving for x/y)
