Answer

Problem

Determine the value of an expression when e = 10, f = -12, g = -9
\$ (-3e-4f+2g)/(6f) \$

Step

Now substitute e,f,g values in expression

\$ (-3(10)-4(-12)+2(-9))/(6(-12)) \$

Step

After multiplication we get

\$ (-30 + 48 - 18)/(-72) \$

Step

After adding we get

\$ (-48 + 48 )/(-72) \$

Step

After cancellation we get

\$ 0 \$
