Solve for x problems examples
WebExample: Solve 3x−6 = 9. Start with: 3x−6 = 9. Add 6 to both sides: 3x = 9+6. Divide by 3: x = (9+6)/3. Now we have x = something, and a short calculation reveals that x = 5. Like a … WebFeb 20, 2011 · Now, we want to isolate the x's on the same side of the equation. So, how could we do that? Well, there's two ways of doing it. We could subtract these two x's from both sides of the equation. And that would be pretty reasonable. Because then you'd have 5 x's minus the 2 x's. You'd have a positive number of x's on the right-hand side.
