15
(b) 2x + 6 = 16
(d) 8x = 36​

Answer 1

$\huge\tt\colorbox{yellow}{Answer}$

$a) \: 20x = - 100 \\ x = \frac{ - 100}{20} \\ x = - 5$

$b) \: 2x + 6 = 16 \\ 2x = 16 - 6 \\ 2x = 10 \\ x = \frac{10}{2} \\ x = 5$

$c) \: 8x = 36 \\ x = \frac{36}{8} \\ x = 4.5$

Answer 2

Answer:

a. 20x=-100

x=-100/20

x=-5

b. 2x+6=16

2x=16-6

x= 10/2

x=5

c. 8x=36

x=36/8

x= 9/2
