If \( a=2, b=3 \) and \( c=4, \) then find the value of \( 3 a-b+c \).
Given: $a=2, b=3$ and $c=4$.
To do: To find the value of $3a-b+c$.
Solution:
$\because a=2, b=3$ and $c=4$
On substituting these value in $3a-b+c$, we have
$3a-b+c=3( 2)-3+4$
$=6-3+4$
$=10-3$
$=7$
$\therefore$, The value of $3a-b+c=7$
