Eliminating the Brackets

In the equation above, the brackets are nested within the equation. To solve this, we need to eliminate the brackets first. Remember, anything inside the brackets is treated as a single entity. So, distribute the 3 to both terms inside the brackets. This gives us 6x - 3 - 4 = 10. Now, the equation is starting to look simpler.

Isolating the Variable

Next, we need to isolate the variable x. To do this, we'll need to perform operations on both sides of the equation to make the x term the only one on one side. Start by adding 4 to both sides to get 6x - 7 = 14. Then, add 7 to both sides to finally get 6x = 21. Now, we're one step closer to finding the value of x.

Dividing by the Coefficient

The last step is to divide both sides by the coefficient of the x term, which is 6. This will give us x = 3.5. So, the solution to the equation is x = 3.5. Remember, this is just one method to solve multi-step linear equations. The secondary 3 math syllabus Singapore covers several methods, so it's essential to practice and understand them all.

Checking the Answer

After solving the equation, it's always a good practice to check if the answer is indeed correct. Substitute x = 3.5 back into the original equation. You should get 3(2*3.5 - 1) - 4 = 10, which holds true. If it doesn't, you might have made a mistake in your calculations. So, always check your work to ensure your answer is correct.
