We are distributing the "3" over the terms in the parentheses

3(4x + 2y) + 5x =

3*4x + 3*2y + 5x =

12x + 6y + 5x [ combine like terms ]

17x + 6y

Here's one way to check your work for these...

Let x = 1 and let y = 1

We want to evaluate the original expression, first

3 [ 4(1) + 2(1) ] + 5(1)

3 [ 4 + 2 ] + 5

3[6] + 5 = 18 + 5 = 23

Now....evaluate the final answer

17(1) + 6(1) =

17 + 6 = 23

Since the answers are the same.....we have it correct
