Identify the equation as an identity, inconsistent equation or conditional equation.
13/2x=7/4
my answer is it is an inconsistent equation

sure looks very consistent to me
13/2x=7/4
(3/2)x = 7/4  1
(3/2)x = 3/4 (times 4 )
6x = 3
x = 1/2
What is a conditional equation?

This is rather about the concept:
1) Identity means both sides are equal no matter what the value x will take.
example: 2+x=x+2
2) inconsistent: means the equation is not true regardless the x value.
example: 2+x=3+x
3) conditional: The equation is true at certain x value.
example: x+2=5, it is true if x=3.
Make sense?
