Answer

$35$

Work Step by Step

You are given the expression $5x$, in which $x$ is a variable, meaning its value could be basically anything, however the value of $x$ in this particular question is given to you; $x=7$ So, substitute this value for $x$ into the original expression to get to the answer. $5x$ ($5x$ means $5$ multiplied by whatever value $x$ is) $= 5\times (7)$ $= 35$
