Question

Q no 3 of 3


please give me full solution ​

Answer 1

Answer:

(i) -3

(ii) 3

(iii) 13

Step-by-step explanation:

(i) -8p-4=20

-8p=24

p=-24/8

p=-3

(ii) -7a+4=-17

-7a=-21

7a=21 (minus-minus cancelled)

a=21/7

a=3

(iii) 3p+5(2-p)=-16

3p+10-5p=-16

-2p=-16-10

-2p=-26

2p=26 (minus-minus cancelled)

p=26/2

p=13

Answer 2

Answer:

$3p + 5(2 - p) = - 16$

$3p + 10 - 5p = - 16$

$3p - 5p = - 16 - 10$

$- 2p = - 26$

$p = - 26 \div - 2$

$p = 13$
