Click to expand...

4 + 4x = 8
 
Next year in High School I am So paying Attention In Math Class..im repeating the same algebra i did in 8th grade my teacher said i should plus i wanted to hehe
 
ok..im giving myself a problem.. 3x+2=12
1) add the opposite of 2 which is -2,
2)add the negative two to twelve which you subtract and then get 10
3)1/3 x 1/10

im stuck..
 
3x + 2 = 12

If the left hand side is the same number as the right hand side, then two less than the left hand side is surely the same number as two less than the right hand side. Subtract 2 from both sides.

(3x + 2) - 2 = 12 - 2
3x = 10

Divide both sides by 3.

(3x) / 3 = 10 / 3
x = 10 / 3
 
If you're not told to do, then you don't have to do. But if you want to write it as a mixed number instead of an improper fraction, you could say:

x = 10 / 3
= (9 + 1) / 3
= 9 / 3 + 1 / 3
= 3 + 1/3
 
You're depressing me, Black Cat...

If you can't understand that 10/3 = 3 1/3, then you need to
repeat stuff much earlier than Algebra 1.
