What does x equal in 4x-9-3.5x-9 ?

Mathematics

Oksi-84 [34.3K]3 years ago
6 0

Answer:

X=0

Step-by-step explanation:

I believe you meant 4x-9=3.5x-9, and I make this assumption due to it being impossible to "solve for x" in the format you gave. The only possibile solution to the question you gave is to simplify it, which would be 0.5x-18.

However, going with what I believe you meant, x would have to equal 0. There's no other possibility besides this, as 0 is the obvious option. Multiplecation by 0 will always produce 0. For 4x-9 AND 3.5x-9 to produce the same value, you'd have to make the variable a number that, when multipled by its coefficient, will produce an identical value. X=0 is the only number that fits this bill.

Jake and Danny agree to share the cost of renting a house for $1100. If Jake agrees to pay $250 more than Danny, how much money
SVEN [57.7K]

Step-by-step explanation:

First divide 1100 by 2

550

Now that would be the amount the both of them would have to pay if they were splitting it equally. Since there not add 250 to 550.

250+550=800

Finally subtract 250 from 550

550-250=300

Jake has to pay $550

Danny has to pay $300
