Question

$148=2(2x+x)n$, then what is the value of $\left(3n\right)2x$ $-193$ ?

• A. - 118
• B. - 45
• C. 45
• D. 118

Answer 1

The correct option is B - 45

Rearranging the given equation, we find :

$148=2(2x+x)n$

$148=2\left(3x\right)n$

$148=3n\left(2x\right)$

Therefore we can plug 193 into the expression we want to find

$3n\left(2x\right)-193=148-193=-45$.
