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.
Without knowing the plus or minus values of the given terms and without any equality signs it can't be considered as a system of equations.
Using the elimination method, 3x + (2y) times 18x - 3y - 5 gives the result of 36xy + 3x - 3y - 5.
x2+3x = 7 x2+3x-7 = 0 Using the quadratic equation formula:- x = -4.541381265 or x = 1.541381265
(3x+4)(3x-4)=0 x=±4/3

Using the elimination method, 3x + (2y) times 18x - 3y - 5 gives the result of 36xy + 3x - 3y - 5.
3(3x - 5y)(3x + 5y)
If you mean: 3x-4y = 19 and 3x-6y = 15 Then: x = 9 and y = 2
2x-y=3 2/3x-y=-1
It is 14*(3x + 2y)
x2+3x = 7 x2+3x-7 = 0 Using the quadratic equation formula:- x = -4.541381265 or x = 1.541381265
First take out -3x to make-3x(x2+11)If you're not using imaginary numbers, then you're done. Otherwise factor x2+11 using the sum of two squares rule.-3x(x-sqrt(11)i)(x+sqrt(11)i)
(3x+4)(3x-4)=0 x=±4/3
4y
3x + 3x + 3x = 3* (3x) = 9x
