Question

A number was added a 7.1. This result was then multiplied by 4 and that total was then divided by 9.4. lf the quotient was -2, what was the number

Answer 1

(4(n+7.1))/9.4=-2

4n+28.4=-18.8

4n=-47.2

n= 11.8

Answer 2

$\frac{(x + 7.1) \times 4}{9.4} = - 2 \\ \frac{4 \times x + 28.4}{9.4} = - 2 \\ 4 \times x + 28.4 = ( - 2) \times 9.4 \\ 4 \times x = - 18.8 - 28.4 \\ 4 \times x = - 47.2 \\ x = \frac{ - 47.2}{4} \\ x = - 11.8$
