50 - 3n = 7n + 80I need help on the steps on doing this problem??

1 answer:

6 0

50 - 3n = 7n + 80
+3n +3n ( add 3n to both sides)
50 = 10n + 80
-80 -80 (subtract 80 from both sides)
-30 = 10n (divide both sides by 10)
n = -3

Given:

The equation is

$\left(z+\dfrac{6}{7}\right)+\dfrac{2}{14}=-1$

To find:

The solution of the given equation.

Solution:

We have,

$\left(z+\dfrac{6}{7}\right)+\dfrac{2}{14}=-1$

It can be written as

$\left(z+\dfrac{6}{7}\right)+\dfrac{1}{7}=-1$

$\left(z+\dfrac{6}{7}\right)=-1-\dfrac{1}{7}$

Multiply both sides by 7.

$7z+6=-7-1$

$7z+6=-8$

$7z=-8-6$

$7z=-14$

Divide both sides by 7.

$z=\dfrac{-14}{7}$

$z=-2$

Therefore, the value of z is -2.
