Chapter 0.5, Problem 7E

To determine

To solve the equation $\frac{12}{5}f=-18$

Answer to Problem 7E

  $f=\frac{-15}{2}$

Explanation of Solution

Given Information: $\frac{12}{5}f=-18$

Formula Used : Linear equations with one variable

Calculation:

Given equation is

  $\frac{12}{5}f=-18$

To isolate the variable f, multiply by $\frac{5}{12}$ both sides-

  $\frac{5}{12}\times \frac{12}{5}f=-18\times \frac{5}{12}$

To simplify further, write 18 and 12 as product of its factors-

  $f=-3\times 2\times 3\times \frac{5}{2\times 3\times 2}$

Hence the final answer is-

  $f=\frac{-15}{2}$
