Answer:

8x = 32

x = 4

y = 6

Step-by-step explanation:

2.5y + 3x = 27

5x – 2.5y = 5

_____________

8x = 32 (equation obtained after adding the two equations)

x = 32/8

x = 4

Plug x = 4 in 2.5y + 3x = 27

2.5y + 3*4 = 27

2.5y + 12 = 27

2.5y = 27 - 12

2.y5= 15

y = 15/2.5

y = 6

7. Find an equation of the line that has slope - 2/3 and which passes through (-1,-4)
labwork [276]

Answer:

y+4=-2/3 (x+1)

Step-by-step explanation:

-1 = x1

-4 = y1

m = -2/3

slope - intercept form = y - y1 = m(x - x1)

y-(-4) = -2/3(x - (-1))

y + 4 = -2/3(x +1)
