Answer:

Hope it helps, and hope it's correct for you

Step-by-step explanation:

I) 7a +13÷21 = 15

First we Collect like terms and do LCM

7a = 15- 13÷21 LCM of 7,15,13÷15= 105

21a= 7- 65 =21a =7-65

105

21a= -58

21 21

a= -2.8

II) 2c -8 = -14

2c = -14 + 8

$\frac{2}{2} = \frac{ - 6}{2}$

c= -3
