5x + (3y-x) + (10-2y) = 5x + 3y - x + 10 -2y = 5x - x + 3y - 2y + 10 = 4x + y +10
so -3y = 11 ie y = -11/3 or -3 and 2/3
The solution of 4x plus 3y -9 and x -3 is; 5x+3y-3.
x=2 y=7 5x+3y= 5 7 x 2 x 3 ____ _____ 10 21 21 + 10 _______ 31
"Like terms" are terms that have the same variables, but possibly with different numbers. "Collect" means to put them together - add the numbers. For example, in an expression such as: 5x + 3y - 2x You can combine the "x" terms: (5x - 2x) + 3y and add the numbers (this is justified by the distributive property: (5x - 2x) + 3y = (5 - 2)x + 3y = 3x + 3y
5x + (3y-x) + (10-2y) = 5x + 3y - x + 10 -2y = 5x - x + 3y - 2y + 10 = 4x + y +10
so -3y = 11 ie y = -11/3 or -3 and 2/3
If you mean: 5x+2y+x-3y then it is 6x-1y
-x+3y+6x-6y=5x-3y
5x+3y
5x + 3y - 2 - x + y + 2 = 4x + 4y = 4(x + y)
This question is missing crucial information. Specifically the mathematical operators... as in +, -, x, /,=... and so on. POSSIBLE INTERPRETATIONS OF QUESTION: 5x-3y=6 ---> SLOPE= 5/3 5x+3y=6 ---> SLOPE= -5/3 5x*3y=6 ---> SLOPE= Not Applicable (Rational Function) 5x/3y=6 ---> SLOPE= 5/18 5x=3y-6 ---> SLOPE= 5/3 5x=3y+6 ---> SLOPE= 5/3 5x=3y*6 ---> SLOPE= 5/18 5x=3y/6 ---> SLOPE= 10/1 I hope one of these worked.
How do you add 2x plus 3y equals 18 in 5x-y equals 11
(3x + 2y)(5x - 3y) Apply FOIL. F(First) ; 3x X 5x = 15x^(2) O(Outside) ; 3x X -3y = - 9xy I(Inside) ; 2y X 5x = 10xy L(Last) ; 2y X - 3y = - 6y^(2) 15x^(2) - 9xy + 10xy - 6y^(2) Collect 'like' terms 15x^(2) + xy - 6y^(2) The answer!!!!!!
5x - 3y -7x + 2y +3x = (5-7+3)x + (-3+2)y = x - y
The solution of 4x plus 3y -9 and x -3 is; 5x+3y-3.
