Question

(i) 6 - 9 = 2y + 15
(ii) b + 3 = 33 -b​

Answer 1

i) 6 - 9 = 2y + 15

-3 = 2y + 15

-3 - 15 = 2y

-18 = 2y

y = $\Large \sf \frac {-18}{2}$

y = -9

ii) b + 3 = 33 - b

b + b = 33 - 3

2b = 30

b = $\Large \sf \frac {30}{2}$

b = 15

Answer 2

Answer:

Given that

==6-9=2y+15

= -3=2y+15

=2y=15-3

=2y=12

{y=6}

==b+3=33-b

=b+b=33-3

=2b=30

{b=15}

Hence proved//
