Answer:
-27x+63
Step-by-step explanation:
you do -9 times 3x then -9 times -7, two negatives creates a positive, and so 9 times 7 equals 63
hope this helps :^)
-9(3x-7)
Multiply each term in the parentheses by -9
-9×3x-9×(-7)
Calculate the product
-27x-9×(-7)
now we do the same thing only different way ok
-9×3x
Multiplying a negative and a positive equals a negative : (-)x(+)=(-)
-(9×3)x
Multiply the numbers
-27x
-9×3x-9×(-7)
Multiply the numbers
-27x+63
Now we do the same thing only different way ok
-9×(-7)
Multiply two negatives equals a positive: (-)×(-)=(+)
9 × 7
multiply the numbers
63
Solution: -23x+63
