Answer 5

6

Answer 6

Good so we have 6x
3 times 8 =?

Answer 7

24

Answer 8

6x+24=0
we subtract 24 from both sides so that we can isolate x
\[\huge~\rm~~6x+24−24=0−24\]
We get our new equation
\[\huge~\rm~6x=-24\]
6 div 6 =1 x i alone
\[\huge~\rm~-24\div6=?\]

Answer 9

-4

Answer 10

good so x=-4
