x=14

Step-by-step explanation

3x/-8=-21/4

Simplify the equation using cross-multiplication

12x=168

Divide both sides of the equation by 12

So first we want to get rid of the fraction to do this we can times by the reciprocal, in this case -8/3x
-8/3x(3x/-8) cancels out to equal 1
1= -21/4
-8/3x(-21/4) is equal to 14/x
times both sides by 14
14= x
To double check we can plug this into the equation

3(14)
42/-8 we can simplify this by diving by 2
21/-8= -21/8 these are the same
