Question

Evaluate the expression, when y = 2.4y - 6 + 5y/y

Answer 1

Given the expression:

`4y\text{ - 6 + }(5y)/(y)`

To evaluate the expression when y = 2, all you have to do is to substitute 2 for y in the expression.

Substituting, we have:

`4(2)\text{ - 6 + }(5(2))/(2)`
`\text{ 8 - 6 + }(10)/(2)`
`\begin{gathered} 8\text{ - 6 + 5 } \\ =\text{ 7} \end{gathered}`
