Question

( x/2 + 7 ) is three times ( x/5 + 2 ). Find the value of x

Answer 1

Answer:

Given that

x/2+7=3(x/5+2)

x/2+7=3x/5+6

6x-5x/10=-1

x/10=-1

x=-10

Answer 2

Answer:

$\frac{x}{2} + 7 = 3 \times ( \frac{x}{5} + 2) \\ \frac{x + 14}{2} = 3 \times ( \frac{x + 10}{5} ) \\ \frac{x + 14}{2} = \frac{3(x + 10)}{5} \\ \frac{x + 14}{2} = \frac{3x + 30}{5} \\ 5(x + 14) = 2(3x + 30) \\ 5x + 70 = 6x + 60 \\ 70 - 60 = 6x - 5x \\ \boxed{ \large \underline{ \underline{ \bf 10}} = x}$
