Tonya saved $564 in one year, if she saved the same amount each month, how much did Tonya save in two months?

So the first thing we do is to multiply the top equation by 3. the reason i want to do this is i notice there will be a 6y on both equations and can possibly add/subtract them. so we get 6y = -3x + 27. adding that and the second equation we get 6x = 27-15 which is 12. divide by 6 and we get 2. ∴ x = 2. substituting 2 into the first equation we get 2y = -2 + 9 which is 7. divide by 2 and we get 7/2. ∴ y = 7/2, x = 2.

Where is the expression you want us to evaluate?

Ithink it may be 10^3,that mean 10 'exponent ^3 would the population scientific in terms to evaluate by such and
