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

OpenStudy (anonymous):

x=27/4

OpenStudy (anonymous):

can u show me how u got tht please

OpenStudy (anonymous):

2x/3 - 4 =1/2 (2x - 12)/3 =1/2 2 * 2x - 2 *12 =3 4x = 27

OpenStudy (dumbcow):

Add 4 on both sides \[\rightarrow \frac{2}{3}x = \frac{2}{4} +4\] Combine fractions on right side \[\rightarrow \frac{2}{3}x = \frac{2}{4} +\frac{16}{4} = \frac{18}{4}\] Multiply by (3/2) on both sides \[x = \frac{18}{4}*\frac{3}{2} = \frac{27}{4}\]

wht key do I press to stand my fraction like you have

OpenStudy (dumbcow):

use "frac{top }{bottom} "

You can also solve this problem without fractions if you decide to multiply both left and right side of the equal side by the LCD. The denominators are 3 and so your LCD is 12. So you multiply your equation by 12 and you get: 8x - 48 = 6 8x = 54...Add 48 to both sides x = 54/8...Divide both sides by 8 x = 27/4...Reduce fraction by factor of 2.

I would first get rid of the fractions 2x/3 -4 = 2/4 12(2x/3 -4) =12( 2/4) 8x-48 = 6 8x = 6 + 48 8x = 54 8x/8 = 54/8 x = 54/8 = 6.75 = 6 3/4 = 27/4
