Step-by-step explanation:

you started by expanding the bracket 3 (2x+6) became 6x+18./

Then you rearranged the equation so like terms were together.

You put brackets around the like terms so (27+18) + (6x+2x)

You added the first like terms (27+18) = 45

then you added the second like terms (6x+2x) = 8x
