GCSE Maths - How to Solve Algebraic Equations (Part 1 of 3) #43

The video tutorial covers basic algebraic equations with one unknown variable. It explains how to solve equations involving addition, subtraction, multiplication, and division by isolating the unknown variable. The key rule emphasized is that any operation performed on one side of the equation must be done to the other side to maintain equality. The tutorial provides examples and practice problems to reinforce these concepts.

What is the main goal when solving basic algebraic equations with one unknown?

• To guess the value of the unknown

• To add numbers to both sides

• To find the value of the unknown letter

• To multiply both sides by zero

When rearranging an equation, what must you remember to do?

• Subtract 10 from both sides

• Do the same operation to both sides

• Only change one side of the equation

• Add 10 to both sides

In the equation X + 3 = 10, what operation should be performed to isolate X?
