Question

8 x - 15 + 7x = 2x + 50

Answer 1

Ответ: x=5

Пошаговое объяснение:

8x-15+7x=2x+50

8x+7x-2x=50+15

13x=65

x=65:13

x=5

Answer 2

To solve the given equation $8x - 15 + 7x = 2x + 50$, you'll first want to combine like terms and simplify both sides of the equation. Here's how you can do it step by step:

1. Combine the x terms on the left side: $8x + 7x = 15x$.
2. Combine the constant terms on the left side: $-15$.
3. Move the constant term from the right side to the left side by subtracting $2x$ and $50$ from both sides:

$$15x = 2x + 50 + 15$$

4. Simplify the right side: $15x = 2x + 65$.
5. Move $2x$ from the right side to the left side by subtracting $2x$ from both sides:

$$15x - 2x = 65$$

$$13x = 65$$

6. Solve for $x$:

$$x = \frac{65}{13}$$

$$x = 5$$

So, the solution to the equation $8x - 15 + 7x = 2x + 50$ is $x = 5$.
