Solve for x. Express the answer in simplest form.1/7=3/4x=1

Sagot :

Okay, so after a bit of research the original equation seems to be:
1/7=3/4x-1

To solve, we need to isolate x on one side. Let's by adding 1 to both sides (and thus eliminate  -1):
1/7+1=3/4x
8/7=3/4x

Let's now multiply by 4 both sides (to eliminate the denominator 4):
4*8/7=3x
32/7=3x

Let's now divide both sides by 3 (to eliminate the 3 from 3x):
32/(7*3)=x
32/21=x
We conclude that x=32/21  or 1 11/21
