Question

If $a=2$ and $b=3$, find the value of $2a-3b$.

Answer 1

Given that,

$a=2\text{and}b=3$

To evaluate:

$2a-3b......\left(i\right)$

Substituting the values of $a$ and $b$ in $\left(i\right)$, we get:

$2\left(2\right)-3\left(3\right)$

$\Rightarrow 4-9=-5$

$\therefore 2a-3b=-5$

Hence, if $a=2$ and $b=3$, the value of $2a-3b$ is $-5$.
