Answer:
x=10
Step-by-step explanation:
5.4=0.3x+2.4
5.4-2.4=0.3x
3=0.3x
Dividing both sides by 0.3
x=10
a=6, b=2
Step-by-step explanation:
Use simplification into substitution
![\frac{a}{3} =1+\frac{2}{b}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7B3%7D%20%3D1%2B%5Cfrac%7B2%7D%7Bb%7D)
![a=3(1+\frac{2}{b})](https://tex.z-dn.net/?f=a%3D3%281%2B%5Cfrac%7B2%7D%7Bb%7D%29)
![a=3+\frac{6}{b}](https://tex.z-dn.net/?f=a%3D3%2B%5Cfrac%7B6%7D%7Bb%7D)
We can now plug this value of <em>a</em> into the second equation.
![\frac{3+\frac{6}{b} }{4} +\frac{3}{b} =3](https://tex.z-dn.net/?f=%5Cfrac%7B3%2B%5Cfrac%7B6%7D%7Bb%7D%20%7D%7B4%7D%20%2B%5Cfrac%7B3%7D%7Bb%7D%20%3D3)
Get rid of fractions in the numerators and/or denominators
![\frac{3b+6}{4b} +\frac{3}{b} =3](https://tex.z-dn.net/?f=%5Cfrac%7B3b%2B6%7D%7B4b%7D%20%2B%5Cfrac%7B3%7D%7Bb%7D%20%3D3)
Then we can match the denominators
![\frac{3b+6}{4b} +\frac{12}{4b} =3](https://tex.z-dn.net/?f=%5Cfrac%7B3b%2B6%7D%7B4b%7D%20%2B%5Cfrac%7B12%7D%7B4b%7D%20%3D3)
Combine
![\frac{3b+18}{4b} =3](https://tex.z-dn.net/?f=%5Cfrac%7B3b%2B18%7D%7B4b%7D%20%3D3)
Divide both sides by three
![\frac{b+6}{4b} =1](https://tex.z-dn.net/?f=%5Cfrac%7Bb%2B6%7D%7B4b%7D%20%3D1)
Get rid of fractions
![b+6=4b](https://tex.z-dn.net/?f=b%2B6%3D4b)
Single out <em>b</em>
![6=3b](https://tex.z-dn.net/?f=6%3D3b)
![b=2](https://tex.z-dn.net/?f=b%3D2)
Now we can plug it into the equation
![\frac{a}{3} -\frac{2}{2} =1](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7B3%7D%20-%5Cfrac%7B2%7D%7B2%7D%20%3D1)
![\frac{a}{3} =2](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7B3%7D%20%3D2)
![a=6](https://tex.z-dn.net/?f=a%3D6)
Now we can check it;
![\frac{6}{3} -\frac{2}{2} =1](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B3%7D%20-%5Cfrac%7B2%7D%7B2%7D%20%3D1)
↑CORRECT
![\frac{6}{4} +\frac{3}{2} =3](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B4%7D%20%2B%5Cfrac%7B3%7D%7B2%7D%20%3D3)
↑CORRECT
Answer:
The answer is A. -5
Step-by-step explanation:
Write out the equation:
-3 + c = -8 Add 3 on both sides to isolate the varible on one side
c = -5 -8 plus 3 is -5
You must isolate the variable in order to solve equations with variables.
Isolating variable is basically when you divide, multiply, add, or subtract to put a variable on <u><em>ONLY </em></u>one side of the equation.
