Question 65

Express the given statement as an equation.

If 1 is subtracted from a number and the difference is multiplied by $\frac{1}{2},$ the result is 7.

Answer 1

Let the number be x.
Then, 1 is substracted from a number and the difference is multiplied by $\frac{1}{2}$ i.e. $\frac{1}{2}(x-1)$
It gives result 7.
So, the equation formed is $\frac{1}{2}(x-1)=7$
