Answer:
I don't know if this is right but here is what I did.
Explanation:
6x+26x-10=8(4x+10)
distribute 8 into the parenthesis.
-> 6x+26x-10=32x+80
add 10 to both sides in order to cancel it out from the left side.
-> 6x+26x=32x+90
6x and 26x are common factors. So, we add them.
-> 32x=32x+90
subtract 32x from right side to leave 90 alone.
-> x=90.
Let me know if this is right?
