Question

solve 4/5x-2/15x=x-3/7​

Answer 1

Answer: x in (-oo:+oo)

(4/5)*x-((2/15)*x) = x-(3/7) // - x-(3/7)

(4/5)*x-((2/15)*x)-x+3/7 = 0

(4/5)*x+(-2/15)*x-x+3/7 = 0

3/7-1/3*x = 0 // - 3/7

-1/3*x = -3/7 // : -1/3

x = -3/7/(-1/3)

x = 9/7

x = 9/7

Step-by-step explanation:

Answer 2

$\frac{4}{5}x$-$\frac{2}{15}x$ = x-$\frac{3}{7}$

Taking LCM of 5 and 15

=> $\frac{12x-2x}{15}$ = x-$\frac{3}{7}$

=> $\frac{10x}{15}$= x-$\frac{3}{7}$

=> $\frac{2x}{3}$=x-$\frac{3}{7}$

=> x-$\frac{2x}{3}$=$\frac{3}{7}$

=> $\frac{3x-2x}{3}$= $\frac{3}{7}$

=> $\frac{x}{3}$= $\frac{3}{7}$

=> 7x= 9

=> x=$\frac{9}{7}$
