Answer

Problem

Determine the value of an expression \$ (-6 + 3k)/(2k) \$ when k=4

Step

Now substitute "k" value in expression

\$ (-6 + 3(4))/(2(4)) \$

Step

After multiplication we get

\$ (-6 + 12)/8 \$

Step

After cancellation

\$ \cancel6^3/\cancel8^4 \$

Step

After simplification

\$ 3/4 \$
