Problem

Determine the value of an expression when x = 0, y = 9, z = 3
\$ (2x+y+3z)/(4y) \$

Step

Now substitute x,y,z values in expression

\$ (2(0) + 9 + 3(3))/(4(9)) \$

Step

After multiplication we get

\$ (0 + 9 + 9)/(36) \$

Step

After adding we get

\$ \cancel18^1/\cancel36^2 \$

Step

After cancellation we get

\$ 1/2 \$
