algebra
It would help if you proofread your questions before you posted them. I assume the top equation is -4x+3y = 3. Multiply that equation by 3. I assume the second equation is 7x + 9y = 6. -12x + 9y = 9 7x - 9y = 6 Add the two equations. -5x = 15 Take it from there.

I don't know what you mean by a "running number." If you want a measure of central tendency for a relatively normal distribution, calculate the mean. It functions as a fulcrum (balance point) for the distribution.
