Answer:
Step-by-step explanation:
A. 4 + 7x + 6 = 3x + 10 + 4x.....combine like terms
7x + 10 = 7x + 10
B. 3x - 12 + 4x = 8 + 7x - 20.....combine like terms
7x - 12 = 7x - 12
C. 7x + 12 = 6 + 7x + 6.....combine like terms
7x + 12 = 7x + 12 <====7x = 7x and 12 = 12 <=== ur answer
D) 1 + 6x + 11 = 16 + 6x - 2...combine like terms
6x + 12 = 6x + 14
