This is the problem and I will explain how to work it out -
5(6x−2)+9=179
30x + −10 + 9=179
The reason I did this working is because 5 x 6x = 30x, so I simplified it to just say 30x. 5 x -2 = -10, so I combined those as well. I also needed to add on the 9 at the end still. This got me to 30x + -10 + 9 = 179
30x -1 + 1 = 179 + 1
Now I am making this a balanced equation. -10 + 9 = -1, so I simplified it again. After I had done this, I used -1 to make this a balanced equation.
30x = 180 30x/30 = 180/30
Now I divide to work out the value of x. 30x/30 equals x. So 180/30 = the value of x.
180 divided by 30 is 6, so that is the value of x.
x=6
I have liked algebra this week, and the group work has been ok. Can't wait for more maths next week!!! : /
