Question

Add 3b-7c+10;5c-2b-15;15+12c=b

Answer 1

Step-by-step explanation:

$(3b - 7c + 10) + (5c - 2b - 15) + (15 + 12c - b) \\ = 3b - 7c + 10 + 5c - 2b - 15 + 15 + 12c - b \\ = 3b - 2b - b - 7c + 5c + 12c + 10 \\ = 3b - 3b + 10c + 10 \\ = 10c + 10 \: (or) \: 10(c + 1)$

Answer 2

Answer:

10c+10=10(c+1)

Step-by-step explanation:

(3b−7c+10)+(5c−2b−15)+(15+12c−b)

=3b−7c+10+5c−2b−15+15+12c−b

=3b−2b−b−7c+5c+12c+10

=3b−3b+10c+10

=10c+10(or)10(c+1)
