Question

1. Each equation is followed by the values of the variable Decide whether these values are the solution of that equation
1.)9m=81, m= 3,9,-3
2)2a+4=0, a=2,-2,1
3) x-4=3,x=-1,7,-7
4)3-y=4, y=-1,1,2​

Answer 1

Answer:

1) m =9 , since 9×9 = 81

similarly the following,

2) 2a +4=0, a=-4/2=-2 , a=-2

3) x=3+4=7

4) -y=4-3=1, y= -1
