Question 68
What is the value of a in the following equation?
$$34 + 16 - a \times [40 \div 5 - 3] - 15$$
Solution
$$34\ +\ 16\ -\ a\times\ \left[40\ \frac{\ 5}{ }-3\right]\ -\ 15$$
$$50\ -\ a\times\ \left[8\ -\ 3\right]\ -\ 15$$
$$50\ -\ a\times\ 5\ -\ 15$$
$$50-5a-15$$
$$50\ -\ 15=5a$$
$$35\ \frac{\ 5}{ }=a$$
$$a=7$$
