Answer:

-98x -54

Explanation:

  • Open the parenthesis by multiplying each term of (6x +3 ) by (-18).

7x + 3x - 18(6x + 3) = 7x + 3x -18*6x - 18*3

= 7x + 3x - 108x - 54

  • Combine like terms. Like terms have same variable with same power. 7x ; 3x and (-108x) are like terms. Combine the coefficient of the like terms. 7+3 = 10 & 10 -108 = -98.

= -98x - 54
