Answer:

(2, –3) is a solution to the system of linear equations.

Step-by-step explanation:

3x - y = 9

4 x + y = 5.

Add the equations

7x = 14

x = 2

Substitute it back into either original equation to find x

3(2) - y = 9

6 - y = 9

y = -3

4(2) + y = 5.

8 + y = 5

y = -3

x = 2

y = -3

(2, -3)

(2, –3) is a solution to the system of linear equations.

s344n2d4d5 [400]

Answer:

n = 27

Step-by-step explanation:

14n = 11n + 81 (Given)

14n - 11n = 11n - 11n + 81 (Subtraction Property of Equality)

3n = 81 (Simplify)

$\frac{3n}{3} = \frac{81}{3}$ (Division Property of Equality)

n = 27 (Simplify)

Zoey goes to a store an buys an item that costs x dollars. She has a coupon for 15% off, and then a 9% tax is added to the disco

pshichka [43]

Answer:

0.9265x

Step-by-step explanation:

x - 0.15x + 0.09(0.85x)

x is the initial amount, -0.15x is subtracting 15% of the original amount (leaving 0.85x), and 0.09(0.85x) is the 9% tax.

Simplified:

x - 0.15x + 0.09(0.85x)

= 0.85x + 0.0765x

= 0.9265x
