+129845 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
+129845 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
