What is the answer to 3x plus 15y equals 33 and 4x-3y equals 66 using the substitution method?
3x + 15y = 33
4x - 3y = 66
3x + 15y = 33 divide by 3 to both sides
x + 5y = 11 subtract 5y from both sides
x = 11 - 5y
4x - 3y = 66, replace x with 11- 5y
4(11 - 5y) - 3y = 66
44 - 20y - 3y = 66 subtract 44 from both sides
-23y = 22 divide by -23 to both sides
y = -22/23
x = 11 - 5y replace y with -22/23
x = 11 - 5(-22/23)
x = 11 + 110/23
x = (11*23 + 110)/23
x = 363/23

Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals", "squared", "cubed" etc. Please use "brackets" (or parentheses) because it is impossible to work out whether x plus y squared is x + y2 of (x + y)2.
X x x x y y y simplify this?
x4y3Answer BIt can be written as x4y3 but it can be switched around such as:4x3y. This means 4 lots of x's and 3 lots of y's or 4x times 3y.Ermm I could be wrong.
