i know the equation to solve it is 5 * (a+40)= 6 * (a-40)
but idk how to solve it step by step

anonymous · Answer

if this eq. is correct then
use the property a(b+c)=ab+ac.

anonymous · Answer

and how do i do that? /:

anonymous · Answer

from the above property we can write it as
5*a + 5*40 = 6*a - 6*40

anonymous · Answer

= 5a+200=6a-240
