Answer:

The number of solutions of an equation is dependent upon the total number of variables contained in it. Thus, the system of the equation has two or more equations containing two or more variables. It can be any combination such as 1. 2 equations in 3 variables 2. 6 equations in 4 variables, and so on Depending on the number of equations and variables, there are three types of solutions to an equation. They are 1. Unique Solution (One solution) 2. No solution 3. Infinite Solutions (Many solutions) The term “infinite” represents limitless or unboundedness. It is denoted by the letter ” ∞ “

Answer: no solution or none

Step-by-step explanation: this is really simple..

1. *DISTRIBUTE THE 2 with the numbers in parantesis* so it’s 6x-8

2. now the equation is 6x-8-6x= -4 (we see a positive and a negative 6 they both cancel each other out)

3. now it’s -8=-4 now add 8 to both sides that will make

0= -4 therefor there is no solution

Simplify 8a-5b-(6a-9b)

pychu [463]

Answer:

Step-by-step explanation:

$8a - 5b - (6a - 9b)$

When there is a (-) in front of an expression in parentheses, change the sign of each term in the expression.

$8a - 5b - 6a + 9b$

Collect like terms

$2a + 4b$

Factor out 2 from the expression

$2(a + 2b)$

Hope this helps...

Good luck on your assignment..

last month , he sold 50 chickens and 30 ducks for $550 . This month , he sold 44 chickens and 36 ducks for $532. How much does a

Kazeer [188]

Hello there, my fellow human being!
So, the chicken costs $8 and the duck costs $5, here's why.

Let's say x is the cost of a chicken while y is the cost of a duck.
We can make two linear equations using the information above.
Last month, he sold 50 chickens and 30 ducks for $550: 50x + 30y= 550
This month, he sold 44 chicken and 36 ducks for $532: 44x + 36y = 532

50x/10 + 30y/10 = 440/10
44x/4 + 36y/4 = 532/4

5x + 3y = 44
11x + 9y = 133

So, now that we have our answer simplified, we have to use elimination to solve this system of equations. But, first we need to make sure that at least one of our variables is able to be canceled out.
Let's multiply this equation by -3.
(5x + 3y = 44) * -3.

-15x-9y=-165.

11x + 9y = 133
-15x - 9y = -165
______________
-4x/4 = -32/4
x = 8
11x + 9y = 133
11(8) + 9y = 133
88 + 9y = 133
-88 -88
________________
9y/9 = 45/9
y = 5.
