Question

Write the following statement in mathematical form using literals, numbers and the signs of basic operations:

"Three times a number $x$ is equal to $12$ less than twice the number $y$."

Answer 1

Writing in mathematical form:

Three times a number $x=3x$

Two times a number $y=2y$

Given , Three times a number $x$ $=$ Two times the number $y$ $-12$

$3x=2y-12$

Hence, the required mathematical form is $3x=2y-12$.
