ii)9-3=7
iii) -13a= 91
iv) 9÷5=3​

Answer 1

Step-by-step explanation:

i) a+10= -18

=>a= -18-10= -28

ii) a-3=7

=>a=7+3=10

iii) -13a=91

=>a=91/-13= -7

iv) a÷5=3

=>a=3×5

=>a=15

Answer 2

Step-by-step explanation:

(I) a = -18 - 10 = -28

(III) a = -91/13 = 7

IN (II) and IV part a is not given .. hence we can not find value.
