Question

0.5 more than three times a number is equal to one less than four times the number. Find the number.

• A. 1.5

Answer 1

The correct option is A 1.5
Let the number be $x$.

0.5 more than three times the number is $3x+0.5$.

1 less than four times the number is $4x-1$.

According to the question,
$3x+0.5=4x-1\Rightarrow 3x-4x=-0.5-1\Rightarrow -x=-1.5\Rightarrow x=1.5$

Hence, the number is 1.5.
