7b=26-5

7b=21

b=3

d) 9a-4=23

9a=23+4

Answer 2

Step-by-step explanation:

Solutions:

a) 4x + 5 = 13

=> 4x = 13 - 5

=> 4x = 8

$= > x = \frac{8}{4}$

=> x = 2 (Ans)

b) 3m - 2 = 7

=> 3m = 7 + 2

=> 3m = 9

$= > m = \frac{9}{3}$

=> m = 3 (Ans)

c) 7b + 5 = 26

=> 7b = 26 - 5

=> 7b = 21

$= > b = \frac{21}{7}$

=> b = 3 (Ans)

d) 9a - 4 = 23

=> 9a = 23 + 4

=> 9a = 27

$= > a = \frac{27}{9}$

=> a = 3 (Ans)

Thank you very much for the thanks
