Question

Simplify and then evaluate the equation when x=4 and y =2

Answer 1

We need to plug in

x = 4

y = 2

into the expression and simplify/evaluate.

Let's evaluate:

`\begin{gathered} 5x+2(9y-x)-y \\ x=4,y=2 \\ So, \\ 5(4)+2(9(2)-(4))-(2) \\ =20+2(18-4)-2 \\ =20+2(14)-2 \\ =20+28-2 \\ =46 \end{gathered}`Answer46
