Determine Whether Each Statement Is An Equation Or Inequality 1. 3x 2013 Y = 9 - Y, 2. 2y +10 = 3x , 3. X 2013 2y < -16 , 4. (X + Y) = 8 , 5. 12 2 5y

Determine whether each statement is an equation or inequality 1. 3x – y = 9 - y

2. 2y +10 = 3x
3. x – 2y < -16
4. (x + y) = 8
5. 12 2 5y + 10 -

 

Answer:

1. (2, 4)

2. (-1/5, 2/5)

3. (1,6)

Step-by-step explanation:

1.

(y = 2x

(x + y = 6

x + 2x = 6

3x = 6

x = 2

y = 2x

y = 2(2)

y = 4

2.

5x + 10y = 3

x = -½y

5(-1/2y) + 10y = 3

-5/2y + 10y = 3

7.5y=3

y=2/5

5x +10y = 3

5x + 10(2/5) = 3

5x + 4 = 3

5x = 3-4

5x = -1

x = -1/5

3.

y - x = 3x + 2 ------- y - 4x = 2 ------- y= 2 +4x

2x + 2y = 14

2x + 2(2 + 4x) = 14

2x + 4 + 8x = 14

10x = 14 - 4

10x = 10

x = 1

y = 2 + 4x

y = 2 + 4(1)

y = 6
