## aj_harleyy one year ago What is an equation that when solved, x= -3

1. Michele_Laino

the simplest equation is: $$x+3=0$$

2. aj_harleyy

i need a harder equation that that to equal -3

3. Michele_Laino

do you mean that x=-3 has to be a solution?

4. aj_harleyy

yes

5. Michele_Laino

another equation, can be this: $\log \left( {{x^2} - 8} \right) = 0$

6. Michele_Laino

where logarithm is taken in any base

7. aj_harleyy

how would i solve that? I don't know how to do log i just started algebra 1

8. AlexandervonHumboldt2

ok here it is: cuberoot(-(x^2+45)/2) here

9. Michele_Laino

sorry! I write another equation

10. aj_harleyy

okay michele

11. Michele_Laino

another eqaution is: $\frac{{x + 3}}{{x - 5}} = 0$

12. aj_harleyy

thamk you very much!
