Evaluate (3x-y)/(3(x-y)) if x = 5 and y = 3. *

mel-nik [20]

Answer:

Step-by-step explanation:

Write the equation

$\frac{3x-y}{3(x-y)}$

Add the variables

$\frac{3(5)-3}{3(5-3)}$

Multiply 3 x 5

$\frac{15-3}{3(5-3)}$

Subtract the parentheses

$\frac{15-3}{3(2)}$

Subtract the numerator

$\frac{12}{3(2)}$

Reduce the fraction with 3

$\frac{12}{3(2)} = \frac{4}{2}$

Reduce the fraction again with 2

$\frac{4}{2} = 2$

And there's your answer of 2!
