Question

Solve the following equations:-
(i) 4 (m+3)= 18
(ii) -2 (x+3)= 5
(iii) 3 (n-5)= 21
(iv) 3 (n-5)= -21
(v) 3-2 (2-y)= 7
(vi) 4+5 (p-1)= 34
(vii) 8 (2-a)= -5a

Please step by step explanation.​

Answer 1

Step-by-step explanation:

1. 4m+12=18

1.4m=18-12=6

m=6/4=3/2 ans

2.-2x+6=5

-2x=5-6=-1

x=-2/-1=2/1 ans

3.3n-15=21

3n=21+15=36

n=36/3=12 ans

5.2-1y=7

1y=7-2=5

y=5/1 ans

9p-9=34

9p=34+9=43

p=43/9 ans

7.16-8a =-5a

-13a =16

a=16/-13 ans
