2x + y = 3 and y = 5x - 11
1) Plug the second equation for y into the first
2) 2x + (5x - 11) = 3
3) Solve for X
4) 7x = 14
5) x = 2
6) Plug X into either equation to get Y
7) 2(2) + y = 3
8) y = -1

What are the factors for number 55?
The first step in finding the factors of a number is to break it down into its prime factors. 55 is known from times tables to be 5x11, so we know its prime factorization is 5x11. To find any factors other than 1, you just multiply any combination of the prime factors together. In this case, 55 gives us the factors of: 1, 5, 11 and 55.

What is one and one fourth times three and two thrids equal?
To multiply two mixed numbers together, you must first convert them into vulgar fractions. This is done by multiplying the units by the denominator and adding the result to the numerator. In this case 1 1/4 would become 5/4, and 3 2/3 would become 11/3 To multiply these together, you multiply both denominators and numerators. So 5x11 = 55. 4x3 = 12. Thus the result is 55/12 This can be converted back into a mixed number as 4 7/12
