​

Answer 1

Step-by-step explanation:

2x/5-3/10=3x/4

We move all terms to the left:

2x/5-3/10-(3x/4)=0

We add all the numbers together, and all the variables

2x/5-(+3x/4)-3/10=0

We get rid of parentheses

2x/5-3x/4-3/10=0

We calculate fractions

There is no solution for this equation

Answer 2

Answer:

$\frac{2x}{5} - \frac{3x}{4} = \frac{3}{10} \\ \\ \frac{8x - 15x}{20} = \frac{3}{10} \\ \\ \\ \frac{ - 7x}{20} = \frac{3}{10} \\ \\ \\ \frac{ - 7x}{2} = 3 \\ \\ - 7x = 6 \\ \\ x = - \frac{6}{7}$
