Today we will solve the linear equation 4x plus 8 equals 20. This is a simple algebraic equation where we need to find the value of x.
The first step is to isolate the variable term. We subtract 8 from both sides of the equation. On the left side, 8 minus 8 cancels out, leaving us with 4x. On the right side, 20 minus 8 equals 12. So we get 4x equals 12.
Now we need to solve for x. We divide both sides by 4. On the left side, 4x divided by 4 gives us x. On the right side, 12 divided by 4 equals 3. Therefore, x equals 3. This is our solution.
Let's verify our answer. We substitute x equals 3 back into the original equation. 4 times 3 plus 8 equals 20. This simplifies to 12 plus 8 equals 20, which gives us 20 equals 20. Since both sides are equal, our solution is correct. x equals 3 is the answer.
