Evaluate the variable expression for x = 5 7 * (x - 8) - 3

OpenStudy (anonymous):

\[7(x-8)-3\]now if \(x=5\):\[7(5-8)-3\]can you solve that? :)

OpenStudy (anonymous):

no

OpenStudy (anonymous):

i'll start you off:\[7(5-8)-3\]subtract within the parenthesis:\[7(-3)-3\]\(7\) times \(-3\) is \(-21\):\[-21-3\]what's \(-21-3\) ?
