Multiply the second equation by 3, so 4x-y=6 becomes 12x-3y=18.

x + 3y = -5
+ (12x-3y = 18)
______________
13x = 13

So x = 1

Plug x = 1 into any of these, such as 1 + 3y = -5, which becomes 3y = -6, and then y = -2.
x = 1
y = -2

Answer:

18.5

Step-by-step explanation:

First find the area of the two triangles.

Find the area of the two top rectangles: 2.5 * 1.7 * 2 = 8.5

Finally, find the area of the floor: 1.5 * 2.5 = 3.75

2.25 + 8.5 + 7.75 = 18.5

Answer:

3. $\displaystyle y = \frac{2}{5}x + 1\frac{2}{5}$

2. $\displaystyle y = -\frac{5}{7}x + 2$

1. $\displaystyle y = -2x + 4$

Step-by-step explanation:

3. 2x - 5y = −7

- 2x - 2x

__________

$\displaystyle \frac{-5y}{-5} = \frac{-2x - 7}{-5} \\ \\ y = \frac{2}{5}x + 1\frac{2}{5}$

2. 5x + 7y = 14

- 5x - 5x

__________

$\displaystyle \frac{7y}{7} = \frac{-5x + 14}{7} \\ \\ y = -\frac{5}{7}x + 2$

1. 6x + 3y = 12

- 6x - 6x

__________

$\displaystyle \frac{3y}{3} = \frac{-6x + 12}{3} \\ \\ y = -2x + 4$
