Step-by-step explanation:
Suppose that 2,4166666 is just 2,416. So the fraction will be 2 in front of a fraction 416 (in nominator) and 1000 ( in denominator) I hooope you understood
Answer:
x=−8
Step-by-step explanation:
−4(2x+3)=2x+6−(8x+2)
−4(2x+3)=2x+6+−1(8x+2) (Distribute the Negative Sign)
−4(2x+3)=2x+6+−1(8x)+(−1)(2)
−4(2x+3)=2x+6+−8x+−2
(−4)(2x)+(−4)(3)=2x+6+−8x+−2 (Distribute)
−8x+−12=2x+6+−8x+−2
−8x−12=(2x+−8x)+(6+−2) (Combine Like Terms)
−8x−12=−6x+4
−8x−12=−6x+4 Add 6x to both sides.
−8x−12+6x=−6x+4+6x
−2x−12=4 Add 12 to both sides.
−2x−12+12=4+12
−2x=16 Divide both sides by -2.
−2x
−2
=
16
−2
x=−8
Answer:
![x=5\ and\ y=-8](https://tex.z-dn.net/?f=x%3D5%5C%20and%5C%20y%3D-8)
The solution of the system can be given as (5,-8).
Step-by-step explanation:
Given system of equations:
![y=-x-3](https://tex.z-dn.net/?f=y%3D-x-3)
![5x+2y=9](https://tex.z-dn.net/?f=5x%2B2y%3D9)
To solve the given system of equations:
Solution:
We will use substitution to solve the given system.
We will substitute the
values in terms of
from the equation
into the other equation to solve for ![x](https://tex.z-dn.net/?f=x)
Substituting
into
.
We have:
![5x+2(-x-3)=9](https://tex.z-dn.net/?f=5x%2B2%28-x-3%29%3D9)
<em>Using distribution.</em>
![5x-2x-6=9](https://tex.z-dn.net/?f=5x-2x-6%3D9)
<em>Combining like terms.</em>
![3x-6=9](https://tex.z-dn.net/?f=3x-6%3D9)
Adding 6 both sides.
![3x-6+6=9+6](https://tex.z-dn.net/?f=3x-6%2B6%3D9%2B6)
![3x=15](https://tex.z-dn.net/?f=3x%3D15)
Dividing both sides by 3.
![\frac{3x}{3}=\frac{15}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B3x%7D%7B3%7D%3D%5Cfrac%7B15%7D%7B3%7D)
∴ ![x=5](https://tex.z-dn.net/?f=x%3D5)
<em>Plugging in
into
.</em>
We have,
![y=-5-3](https://tex.z-dn.net/?f=y%3D-5-3)
∴ ![y=-8](https://tex.z-dn.net/?f=y%3D-8)
The solution of the system can be given as (5,-8).
