Step-by-step explanation:
[tex]10x - 4x + 6x = 12x = 6x + 6x \\ \\ 8(1 + 9y) = 8.1 + 8.9y = 8 + 72y[/tex]
Answer:
12x, 6x+6x for row one
8*1+8×9y, 8+72y for row two
Step-by-step explanation:
10x-4x is 6x, because they're like terms. 6x+6x=12x
Using the Distributive Property, 8(1+9y)=
(8*1)+(8*9y)
=
8+72y
