Answer:
a) 16
b) - x + 9y
Step-by-step explanation:
First, lets simplify problem a.
- 7 + 13 = 6
- 6 + 8 = 2
5 × 2 = 10
6 + 10 = 16
16 would be your answer for problem a.
Next, lets simplify problem b.
First, expand the equation
-4(x + 2y): -4x - 8y = 3x - 4x - 8y + 17y
Then, simplify it
3x - 4x - 8y + 17y = -x + 9y = - x + 9y
- x + 9y would be your answer for problem b.
Hope this helps!!
