When solving these types of questions, we need to find the value of x and y. The only way to do this is to solve.

Take the value of the first equation: x = 1 + 3y and plug it into the second equation.

2(1+3y) - 5y = 3
2 + 6y - 5y = 3
2 + y = 3
y = 1

We know what y equals but we still need to know what x would equal to.
x - 3y = 1
x - 3(1) = 1
x - 3 = 1
x = 4

(x,y) or (4,1)

So, now we obviously have our answer, and I really hope my explanation helped.

Answer would be (4,1)

The difference between one-fifth of a number and 4 is -75

Varvara68 [4.7K]

Think of this as (1/5)x - 4 = -75, where x is the number that we are trying to figure out. To figure this out, we want to get x by itself, so we can go:

(1/5)x=-71
x=-71*5
x=-355

So your number is -355

Choose the correct answers for (a) the total installment price, (b) the carrying charges, and (c) the number of months needed to

Brrunno [24]

Part A:

Given that <span>a dinette table with a cash price of $200 is purchased at $8.50 down and $11.00 per month for 24 months

The total installment price is given by

$P=\$8.50+\$11(24) \\ \\ =\$8.50+\$264=\$272.50$

Part B:

The carrying charges is given by the total installation price minus the cash price.

From part a, we obtained that the total installation price is $272.50 and given that the cash price is $200.

Therefore, the carrying charges is given by

$272.50 - $200.00 = $72.00

Part C:

If the money is to be saved at $11 per month to be able to purchase the table at the cash price, the number of months it will take to be able to save $200 at $11 per month is given by

$\frac{\$200}{\$11} =18.18\, months$

Therefore, it will take 19 months </span><span>to save the money at the monthly rate needed to buy the item for its cash price.</span>
