2 answers:

3 0

$x in (-oo:+oo)

2/7 = 2*x // - 2*x

2/7-(2*x) = 0

2/7-2*x = 0

2/7-2*x = 0 // - 2/7

-2*x = -2/7 // : -2

x = -2/7/(-2)

x = 1/7

x = 1/7$

2X=1 because you subtract 2 from each side to isolate x, and then you get 10x=5. Then divide 5 by 10, which leaves you with x=1/2, so you multiply that by 2 to solve for 2X, which is 1

Solve for the value of x: x/2 + x/3 = 2x/5 + 3 , also I need a very thorough explanation for this.

Answer:

$x=\frac{90}{13} .$

Step-by-step explanation:

$\frac{x}{2} +\frac{x}{3} =\frac{2x}{5} +3;$

$30*(\frac{x}{2} +\frac{x}{3} )=30*(\frac{2x}{5} +3);$

15x+10x=12x+90; ⇔ 13x=90;

$x=\frac{90}{13}.$
