Every time Jason buys 2 red marbles he buys 1 blue marble. If y = the number of red marbles Jason buys, and x = the number of bl
ahrayia [7]

Cary sets up a checking account with an initial balance of $27,700, and the rent for her
jek_recluse [69]

Answer:

$1,650

Step-by-step explanation:

First, we need to find how much she paid the whole year. 27,700-x=7900. If we subtract 7900 from each side and add x to each side, we get 19,800=x. Therefore, she paid $19,800 in rent the whole year. Since there are 12 months in a year, and each month she paid the same, she paid $1,650 in rent each year, for 19800/12=1650

6x + 7y = 13<br> x - 4y=-3<br> Substitution method.
Dovator [93]

Answer:

idk if this is right but if it is right can i have brainliest and if it is wrong then rate me a 1 and you can umm... report me if u want

Step-by-step explanation:

Let's solve for x.

6x+7y=13x

Step 1: Add -13x to both sides.

6x+7y+−13x=13x+−13x

−7x+7y=0

Step 2: Add -7y to both sides.

−7x+7y+−7y=0+−7y

−7x=−7y

Step 3: Divide both sides by -7.

−7x

−7

=

−7y

−7

x=y
