Hey there!:
4r -3 + 6s - 8r - (4s - 6)
*distribute parentheses :
= - ( 4s ) - ( - 6 )
Apply minus - plus rules
- ( - a ) = a ; - ( a ) = - a
= - 4s + 6
4r -3+ 6 s - 8r -4s + 6 =
Group like terms :
=4r - 8r + 6s - 4s -3+6
Add similar elements: 4r - 8r= - 4r
-4r + 6s - 4s- 3+6
6s - 4s = 2s
-4r + 2s - 3 + 6
Add/Subtract the numbers :
-3 + 6 = 3
Therefore:
= 2s +3 - 4r
hope this helps!
