-8.3 + x = -12

I will give brainliest

x = -3.7

Step-by-step explanation:

so in this equation we are trying to find the variable x and to do so we have only have the variables on one side of the equal sign and numbers on the other. SO the equation is:

-8.3 + x = -12

So we are going to only have x on the left side of the equal sign, so we are going to add 8.3 to -8.3 and -12 because what you do to one side you do to the other:

-8.3 + x = -12

+8.3        +8.3

to make the equation look like this:

x = -3.7

Now to check our work we are going to replace where the x variable is in the equation -8.3 + x = -12  with -3.7

-8.3 + (-3.7) = -12

-12 = -12

Hope this helps!!!

for the points! : )
