Eqt 1 = 4a-5b=7
eqt 2 = 4a+5b=17
eqt1+eqt2= 8a=24
a=3 then 4*3-5b=7
so b=1
Answer:
your answer is CCCCCCC
Step-by-step explanation:
First, an equation for the total number of days required to write her paper:
Total = 1493 words + (269 words/day)(x) = 3376 words.
Simplifying, (269 words/day)x = 3376 words - 1493 words
If you solve this linear equation, you'll find that x = 7. That means Amy can finish her paper in 7 days.
