x=8
9999,000,999,000 x 2222222 - 10 + 5 x 200
You can re-express this as: 50 / 80 = x / 100 and then solve for x: 8x = 500 x = 125/2 x = 62.5 So 50 is 62.5 percent of 80.
The letter X in the equation 14 plus X21 would be 2.5. this is a math problem.
You cannot solve 'x' in math unless the other number has a variable as well.
The answer to X 8 times 16 times 6 equals 9216. This is a math problem.
3x - 5x + 4x = -2x +4x = 2x
16 x 4 = 64 16 x 0.5 = 8 16 x 4.5 = 72

The answer to the math problem x 3-2x 2 plus x-4 0 is 0.
111111111111 x 111111111111 is a math problem. To solve this, you have to put it in scientific notation.
To solve x + x + x + x, set the problem up as multiplication like this 4x = 128. Divide both sides of the problem by 4. You will get x = 32. To check your work, substitute 32 for the x and do the math. 4 x 32 = ?. If the answer is 128, the answer is correct.
