(ii) m/6+2=-7

m/6= -9

m = -54

(iii) 2b/3-5= -9

2b/3= -4

2b = -12

b = -6

(iv) 7+3m/4 = -2

3m/4 = -9

3m = -36

m =-12

Answer 2

Step-by-step explanation:

2 (i) b/5+9=13

=> b/5=13-9

=> b/5= 4

=> b= 4×5

•°• b = 20

(ii) m/6+2= -7

=> m/6= -7-2

=> m/6= -9

=>m= -9×6

•°• m = -54

(iii) 2b/3-5= -9

=> 2b/3 = -9+5

=> 2b/3= -4

=> 2b= -12

=> b= -12/2

•°• b=-6

(iv) 7+3m/4= -2

=> 3m/4 = -2-7

=> 3m/4 = -9

=> 3m = -9×4

=> 3m= -36

•°•m = -12
