How do you factor

2 + 2 y + x + x y

https://socratic.org/questions/how-do-you-factor-2-2y-x-xy

(2 + x) (1 + y)

Explanation: Collect

y

btween the second and fourth term:

2 + x + y (2 + x)

(2 + x) + y (2 + x)

How do you factor by grouping

x y + 4 x - 2 y - 8

Gió Apr 15, 2015 Try collecting

y

between the first and third term and

4

between the second and the fourth:

y (x - 2) + 4 (x - 2) =

How do you solve

x + 2 y + z = 6

2 x - y - z = 0

3 x + 2 y + z = 10

using matrices?

https://socratic.org/questions/how-do-you-solve-x-2y-z-6-2x-y-z-0-and-3x-2y-z-10-using-matrices

x = 2

y = 0

z = 4

Explanation: Given -

x + 2 y + z = 6

2 x - y - z = 0

3 x + 2 y + z = 10

Find the number of non-negative integer solutions of

x + y + z = 14

0 \leq x, y, z \leq 9

https://math.stackexchange.com/q/2820340

See that when you make

x \geq 9

others are always less than

9

. So count all possiblities than count possiblites when one of the numbers is greater than

9

and multiply it by

3

and subtract from ...

How do you solve

3 x + 6 y = 9

2 x + 8 y = 10

using substitution?

https://socratic.org/questions/how-do-you-solve-3x-6y-9-and-2x-8y-10-using-substitution

x = 1; y = 1

[Eqn 1] 3 x + 6 y = 9; [Eqn 2] 2 x + 8 y = 10

Multiply [Eqn 1] by 2; [Eqn 2] by 3, so

x

How do you solve the system of equations

2 x + 3 y = 6

3 x + 3 y = 14

x = 8, y = - \frac{1 0}{3}

Our aim is finding a similarity in the two equations. In this problem, we already have it:
