Khan academy algebra equations

Learn how to solve linear equations that contain a single variable. For example, solve 2(x+3)=(4x-1)/2+7. Sal solves the equation -16 = x/4 + 2. It takes two steps because he first has to subtract 2 from both sides and then multiply both sides by 4.

9y = -36 Now I’m going to add to the left side of the equation and the right side of the equation to get a new equation so 5x – Algebraic expressions,

Here’s an introduction to basic algebraic equations of the form ax=b. Remember

Worked example: Learn to solve the equation 2x + 3 = 5x – 2. The core idea in algebra is using letters to represent relationships between numbers without specifying what those numbers are!
