Pause the video now to solve it yourself. Let's break it down together.
We have the equation 8x + 4 = 36. Our goal is to solve for x. We'll first remove the four by subtracting it from both sides. Subtract four from both sides to isolate the term with x. That leaves us with 8x = 32. Now, let's isolate x by dividing both sides by 8.
This undoes the multiplication. Divide both sides by 8. So, x = 4. And there you have it, x = 4. Follow Brain Shorts for more tips.
