0.40 is actually 2/5.
2/5=4/10=8/20=16/40
How did I create all of these fractions?
Quite simple... I multiplied each fraction by 1... What do you mean?
2/5*2/2=4/10
2/2 is one by the way.
4/10*2/2=8/20.
You get the idea?
X + 6 = -8
x = -8 - 6
x = -14
so
-14/1 + 6 = -8
answer
-14/1
11x + y = -28
Make sure to always remember that you can't have any fractions or decimals in standard form.
Standard form is basically
Ax + By = C
