Question: 1-19
Which of the following expressions is equivalent to 2(x - 5) – 3(x – 8) ?
-X – 13
-X + 14
x + 14
X + 19

Answer 1

`1(2)/(3)-2(1)/(3)`

First of all, let us convert the fractions to improper fraction,

`(5)/(3)-(7)/(3)`

Secondly, let us get the Lowest Common Multiple (L.C.M),

To solve for the L.C.M, we need to know the denominators of the fractions.

From the questions, the two denominators are 3. Since the two fractions have the denominator of 3, therefore the L.C.M is 3.

`\begin{gathered} (5)/(3)-(7)/(3) \\ =(5-7)/(3)=-(2)/(3) \end{gathered}`

Hence, the answer of the is:

`=-(2)/(3)`
