Hello there,
Here is your answer,
5x-40=4x-90
we move all terms to the left:
40x+80-(5x+40)
we get rid of parentheses
4x-5x-40+80=0
we add all the numbers together
-1x+40=0
we move all terms containing x to the 1
-x=-40
x=-40/1
[x= + 40]
After getting value of x you can put with 8x
8x =? : .let x = 40
8 (40) = 320 ans
Hope this will help.
Thank you :)
