Question

1/3 * x - 3/4 = 5/2 * x - 2/5​

Answer 1

Step-by-step explanation:

$\frac{1}{3} x - \frac{3}{4} = \frac{5}{2} x - \frac{2}{5} \\ \frac{1}{3} x - \frac{5}{2} x = - \frac{2}{5} + \frac{3}{4} \\ \frac{2x - 3x}{6} = \frac{ - 8 + 15}{20} \\ - \frac{x}{6} = \frac{7}{20} \\ - x = \frac{7 \times 6}{20} \\ x = - 2.1$

Answer 2

Answer:

(1/3)x-(5/2)x=3/4-2/5

x{1/3-5/2}=(15-8)/20

x(2-15)/6=7/20

13x/6=7/20

x=7×6/(13×20)=21/130
