Find the values of x and y if (-x + 5, 1) = (-y, 2x - 5y).
MrMuchimi

Answer:

x = 8, y = 3

Step-by-step explanation:

Equating corresponding x and y coordinates , then

- y = - x + 5 ( multiply through by - 1 )

y = x - 5 → (1)

2x - 5y = 1 → (2)

Substitute y = x - 5 into (2)

2x - 5(x - 5) = 1 ← distribute and simplify left side

2x - 5x + 25 = 1

- 3x + 25 = 1 ( subtract 25 from both sides )

- 3x = - 24 ( divide both sides by - 3 )

x = 8

Substitute x = 8 into (1) for corresponding value of y

y = 8 - 5 = 3

Direct variations look like this (y = 3x_
Not direct variations (or inverse variations) look like this (y= 1/3x.) They are often in fraction form.

So, in your problem the direct variations are: 
y= 3x
x = -1
-0.5x = y
y= 2.2x +7
y= 4

The non-direct variations are:
y = 2/7x
