X divided by half equals five seventh

X divided by half equals five seventh


x/(1/2)=5/7
x=5/7*(1/2)
x=5/14



The solution equations are: x + 1 / 3 x = 28 and X-2 / 3 x = 3 / 4
fast


X + 1 / 3 x = 28
4X of 3 = 28
X = 28 * 3 / 4
x=21
2X of x-3 = 3 of 4
Three out of four x = three out of four
X = 3 / 4 * 3
X = 9 / 4
