Answer:
y = 2x - 3
Step-by-step explanation:
She receives 21. 1/5 of 30 is 6, or the number of picture messages Lilly receives. 7/8 of 24, the number of remaining messages, is equal to 21.
In that case you would need a negative number to cancel the other negative, in a sense -20 i guess or less
The answer is 90 because sum is the answer of a addition problem and 40 + 50 is 90
