To solve the equation 7x = 2x, where x represents the unknown variable, you would first subtract 2x from both sides to isolate x. This leaves you with 5x = 0. Then, dividing both sides by 5 gives you x = 0. Therefore, the value of the blank that satisfies the equation 7 times blank equals 2 times blank is 0.
The answer is three. 6 x 3 = 18

Well, isn't that a happy little math problem we have here? To find the value of "blank," we can simply divide 8 by 0.4 (which is 40% as a decimal). So, 8 divided by 0.4 equals 20. And just like that, we've solved our little equation and created a beautiful mathematical landscape together.

The question "10 blank equals what" is asking for the missing value that would make the equation complete. Without knowing the context or the specific operation intended (addition, subtraction, multiplication, division), it is impossible to provide a definitive answer. It could be solved by filling in the blank with any number that satisfies the equation, such as "10 + 5 equals 15" or "10 divided by 2 equals 5."

There is no "answer", X=6 is complete in itself. There is nothing to solve. What is the value of X? Well, it's equal to 6.
A variable like "x" can have any value. If you have a complete equation, like 9x + 12 = 100, a specific value of x will make the equation true; other values will make it false. But here, you don't have an equation, so any value will do for x.
To solve the equation "x divided by -2 equals 8," we can rewrite it as x / -2 = 8. To isolate x, we can multiply both sides by -2 to get x = 8 * -2, which simplifies to x = -16. Therefore, the value of the blank is -16.
4 × ? × 8 = 64 → 4 × 8 × ? = 64 → 32 × ? = 64 → 32 ÷ 32 × ? = 64 ÷ 32 → ? = 2 The blank needs to be filled by a 2.
It is an equation and the value of a is 7
