Solving the Equation 2x + 3 = 11

To solve the equation 2x + 3 = 11, we use the principles of algebra. First, we want to isolate the variable, x.

Subtract 3 from both sides to get 2x = 8. Then, to solve for x, divide both sides by 2, yielding x = 4.

So, the solution to the equation is x = 4.

In South Africa, Grade 9 students learn to solve such equations using these foundational algebraic principles. This understanding forms a crucial basis for more complex problem-solving in later grades.
