find the like variables
OpenStudy (anonymous):
No! You have to cross multiply! Do you know what that is? You need to take 3 and multiply it with 5x-2 and take 8 and multiply it with x+8
OpenStudy (anonymous):
yes
OpenStudy (anonymous):
3(5x-2)=15x-6 then 8(x+8)=8x+64. After that it is all one big problem, THEN you find like terms. Then your answer.
OpenStudy (anonymous):
So: Find like terms here: 15x-6+8x+64
