Answer:
4x-2(3x-5)+2/3(4x-7)=0
The best way to keep track of where you need to add and subtract is to turn it all into addition by changing a minus to plus a negative.
4x+-6x+-10+8/3x+-14/3+0
Just work with one varible at a time to keep from getting confused.
-2x+-10+8/3x+-14/3=0
2/3x+-10+-14/3=0
2/3x+-16/3=0
You are adding 16/3 to both sides not subtracting. That is where everyone is getting confused.
2/3x=16/3
x=8
To double check insert 8 into the x spot and work out the problem
