Question

Evaluate the expression b= 3/10c= 2/153c-bwrite in the simplest form

Answer 1

$\begin{gathered} b=\frac{3}{10} \\ c=-\frac{2}{15} \end{gathered}$

Evaluate those values into the expression:

$\begin{gathered} 3c-b \\ so\colon \\ 3(-\frac{2}{15})-\frac{3}{10} \\ -\frac{6}{15}-\frac{3}{10}=\frac{-60-45}{150}=-\frac{105}{150}=-\frac{7}{10} \\ \end{gathered}$

Answer:

$-\frac{7}{10}$
