2x+x+47
3x+47
3x+47=x+93
2x+47=93
2x=46
x=46/2
x=23
You must use all the equations that makes up the x. Using all the equations will cover the area than just using part of it.
So regrouping
the teacher doesn't want
14 and 0.1
she wants something to take the decimals apart and whole numbers exg
10.2 +3.9=10+0.2+3+0.9=10+3+0.2+0.9=13+1.1=14.1
some examples are
1.2+12.9
2.4+11.7
3.7+10.4
