Question

Which equation has no solution?

0 14x-21=-6
012-x1=9
O 13x + 61 = 6
O 1-2x+81 = 0

Answer 1

Explanation:

1 , 14x=-6+21

14x=15 , divide both sides by q4 to get the value of x

x=15/14

2 , x1=x

-x=9-12

-x=-3 , divide both side by -1

x=3

3, 13x=6_61

13x= 55 , divide both sides by 13

x=55/13

4, 1-2x+81=1+81_2x

82_2x=0

-2x=-82 , divide both sides by -2

x=41

So, all of them have a solution
