Answer 1

see all are algebraic expnrtions

and between them there is an equal sign

so solve that equation...try to change their sign

from plus to minus

minus to plus

multiplication to devision

and devision to multiplication

similarly

1. a+3=10

therefore 10-3=7

so a=7

2. y+5= -11

therefore -11-5= -16

so y = -16

3. s-8=9

therefore 9+8= 17

so s = 17

simaltaneously..solve others
