Yay! Mine was kind of hard. Here is another one using all the skills that we have learned.
19(3x+21x)=37x+2+4(2x+5)

Any one can give it a try. ツ

467895x + 256761 = 56247 + 6x
467895x = -200514 + 6x
467889x = -200514
x = -0.428550361303643

We have learned a lot of methods on how to solve these problems and I still get confused on when to use each method.

The review

When it is a fraction do you always divide it second?

Reply

The order does not matter but I like to multiply then divide because it is easier for me.

4/5(10)
(4x10)/5
40/5
8

or

4/5(10)
4(10/5)
4(2)
8
