  • b.6a/6+18b/6-12c/6
Blababa [14]3 years ago
6 0

Answer:

8x - 16y and a + 3b - 2c

Step-by-step explanation:

(a)

8(x - 2y) ← multiply each term in the parenthesis by 8

= 8x - 16y

(b)

\frac{6a+18b-12c}{6} ← factor out 6 from each term in the numerator

= \frac{6(a+3b-2c)}{6} ← cancel the 6 on numerator/ denominator

= a + 3b - 2c
