You're on a roll —
Step 1: Distribute the numbers outside the parentheses into the terms inside each parenthesis.
7(x−5)+4(x−2)=(7⋅x+7⋅(−5))+(4⋅x+4⋅(−2))
=7x−35+4x−8
Step 2: Combine the like terms. Group the x terms and the constant terms.
(7x+4x)+(−35−8)
=11x−43
The expanded and simplified expression is:
11x−43
