Distribute the 2 into the 2x and -y
Then add “like terms” which are 3x and 4x... 3y and -2y
Which then becomes 7x+y
There are no more “like terms” so that is your final answer
#8: $900. (I found this answer by multiplying 3000 and 0.3 by the way)
#9: 160 miles. I found this answer by multiplying 80 by two, since two halves/50% make a whole or 100%.
Answer:
No Solution
Step-by-step explanation:
8x+2y=13 4x+y=11 Subtract 4x on both sides to isolate y
y=-4x+11 <---- Substitute this equation into the
equation 8x+2y=13
8x+2(-4x+11)=13
8x-8x+22=13
22=13 (not true)

Jessica is purchasing a new car whose MSRP is $19,750. She is trading in her old car for $8100.
Without the upgrade package and delivery charge , the cost of her car is
19,750 - 8100 = $11650
upgraded cost = $6000 and Vehicle delivery = $600. we add the upgraded cost and delivery cost.
Total cost of car = 11650 + 6000 + 600 = $18,250
