Solving the rational equation
the value of x is 7
Step-by-step explanation:
We need to solve rational equation:
and find value of x.
Solving:
![\frac{3}{x-4}=\frac{7}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7Bx-4%7D%3D%5Cfrac%7B7%7D%7Bx%7D)
Cross multiplying:
![3(x)=7(x-4)\\Simplifying:\\3x=7x-28\\3x-7x=-28\\-4x=-28\\x=-28/-4\\x=7](https://tex.z-dn.net/?f=3%28x%29%3D7%28x-4%29%5C%5CSimplifying%3A%5C%5C3x%3D7x-28%5C%5C3x-7x%3D-28%5C%5C-4x%3D-28%5C%5Cx%3D-28%2F-4%5C%5Cx%3D7)
So, value of x = 7.

Answer:
Step-by-step explanation:
we want y by itself...sooo
y - 19 = -
(x - (-5))
y - 19 = -
(x+5)
y - 19 = -
x - ![\frac{6}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B2%7D)
y = -
x - 3 +19
y = -
x + 16
