Answer 2

To solve for the variable z in the equation:

$\frac{7}{25} - \frac{1}{5}z = \frac{9}{10} + \frac{19}{50}z$,

follow these steps:

Step 1: Get rid of fractions by finding a common denominator for all the fractions involved. In this case, the common denominator is 50.

Step 2: Multiply both sides of the equation by 50 to eliminate the fractions:

$50 \cdot \frac{7}{25} - 50 \cdot \frac{1}{5}z = 50 \cdot \frac{9}{10} + 50 \cdot \frac{19}{50}z$.

Simplify each term:

$14 - 10z = 45 + 19z$.

Step 3: Move all terms involving z to one side of the equation and constants to the other side:

$-10z - 19z = 45 - 14$.

$-29z = 31$.

Step 4: Solve for z by dividing both sides of the equation by -29:

$z = \frac{31}{-29}$.

This is the simplified solution for the equation:

$z = -\frac{31}{29}$.
