What is 6x 4y-8x-10x 5y-9?
7.8.8
What is '6x-5y-2x-3y plus 9x-y'?
86
What expression is equivalent to 7x plus 4y - 9x plus 5y?
It can be simplified to: 9y-2x
How do you solve 6x-4y equals 54 -9x plus 2y equals -69 using substitution?
-9x + 2y = -69 So 2y = 9x - 69 The other equation can be written as 6x - 4y = 54 or 6x - 2*2y = 54 Substituting for 2y gives 6x - 2*(9x - 69) = 54 6x - 18x + 138 = 54 12x = 84 x = 7 and then 2y = 9x - 69 = 9*7 - 69 = 63-69 = -6 so that y = -3
If P equals 2y-6xy-3x and Q equals 4-5y find 2P-3Q and simplify your answer?
2p = 4y - 12xy - 6x, 3q = 12 - 15y so 2p - 3q = 4y - 12xy - 6x - (12 - 15y) = 4y - 12xy - 6x - 12 + 15y = 19y -12xy - 6x - 12
What is the answer of 9x 4y -6x - 5y?
That will depend on the plus or minus value of 4y in order to simplify the given expression
Simplifying rational expressions 6x-5y plus -3x-4y?
(6x - 5y) + (-3x - 4y) =6x - 5y - 3x - 4y =3x - 9y =3 (x - 3y)

2p = 4y - 12xy - 6x, 3q = 12 - 15y so 2p - 3q = 4y - 12xy - 6x - (12 - 15y) = 4y - 12xy - 6x - 12 + 15y = 19y -12xy - 6x - 12
What is the answer to 5x - 4y plus 9y plus x -9 plus 7?
5x-4y+9y+x-9+7 = 5x + x - 4y + 9y - 9 + 7 = 6x + 5y - 2 ■
4y +y?
5y
The order pair for 3x plus 5y equals 21 and -9x plus 4y equals -6?
x = 2, y = 3
What is 5y - y?
5y - y = 4y
