Is the equation true, false, or open? 5x – 10 = 12x + 3

Question

Answer 1

To determine if the equation is true, false, or open, we need to solve it.

5x - 10 = 12x + 3

First, let's combine like terms by subtracting 5x from both sides:

-10 = 7x + 3

Next, let's isolate x by subtracting 3 from both sides:

-13 = 7x

Now, let's solve for x by dividing both sides by 7:

x = -13/7

Since we have found a value for x, the equation is not open.

Therefore, the equation is true.
