Answer 1

For this case we have that by definition, a function is of the form:

`y = f (x)`

So, we have the following system of equations:

`y = -6x + 2\\y = -2x + 4`

Equating the equations we have:

`-6x + 2 = -2x + 4`

Adding 2x to both sides of the equation:

`-6x + 2x + 2 = 4\\-4x + 2 = 4`

Subtracting 2 from both sides of the equation:

`-4x = 4-2\\-4x = 2`

Dividing between -4 on both sides of the equation:

`x = \frac {2} {- 4}\\x = - \frac {1} {2}`

Thus, the value of the variable "x" is -0.5.

Answer:

-0.5
