Question

How do you write the expression for: the sum of twice a number and half the number is 10?

Answer 1

`2x+x/2=10`

Explanation:

2 times a number plus half a number must equal 10, therefore let the number be x. So 2 times x plus half of x is equal to 10
`2(x)+1/2(x)=10`
which is then equal to
`2x+x/2=10`
