Solve y-4=3x+5y for y
Inga [223]
<h3><u>The value of y is equal to (-4 - 3x)/4.</u></h3>

Because there are two variables and only one equation, we cannot solve for the exact value of y.

However, we can still get a value of y.

y - 4 = 3x + 5y

Subtract y from both sides.

-4 = 3x + 4y

Subtract 3x from both sides.

-4 - 3x = 4y

Divide all terms by 4.

(-4 - 3x)/4 = y

Liam uses 2 quarts of yellow paint and adds 3 1/4 Jars of blue paint.Evan uses 1/2 quarts of yellow paint and adds 5 1/2 of red
EleoNora [17]

Answer:

2 + (13/4)x = 1/2 + (11/2)y

Step-by-step explanation:

Let each jar of paint used by Liam be x

Let each jar of paint used by Evan be y.

Liam uses 2 quarts of yellow paints and adds 3 1/4 jars of blue paint. so we have

2 + 3 1/4x

= 2 + (13/4)x

Since Evan also uses 1/2 quarts of yellow paints and add 5 1/2 jar of red paint, we have

1/2 + 5 1/2y

= 1/2 + (11/2)y

Since they end up with the same volume of paint, we have

2 + (13/4)x = 1/2 + (11/2)y

What is the solution set of x2 + y2 = 26 and x − y = 6
jok3333 [9.3K]
The solution set is (9.5, 3.5). Explanation: 9.5(2)+3.5(2) is the same as 19+7 which equals 26. These same numbers are used for x-y=6, which is 9.5-3.5=6.
