x = -2t + 2 = -2(t - 1)
y = t - 1
So x = -2*y or y = -x/2
Also, t = 0 gives x = 2
and t = 4 gives x = -6
so 0 < t < 4 is equivalent to -6 < x < 2.
The answer, therefore is, y = -x/2 for -6 < x < 2
Note:
The t-domain is not well defined since the browser does not show any of the inequalities. I have assumed they are all strict inequalities but if they are not, the corresponding inequalities should be used to define the x-domain. However, it is important to remember that the first inequality in t-domain is the second inequality for the x-domain.
Expression. Equations have equals signs.
There is only one equation, so it's not a system of equations.

Solving equations in two unknowns requires two independent equations. Since you have only one equation there is no solution.
Not until it equals something. Equations have equals signs.
well there are many equations actually.
yes. equations have an equals signs and expressions don't
They are called the solutions or roots of the equations.
Expression. Equations have equals signs.
There is only one equation, so it's not a system of equations.
An equation has an equals sign ( = ). Equations assert the absolute equality of two expressions.

Solving equations in two unknowns requires two independent equations. Since you have only one equation there is no solution.
That equation cannot be solved since there are 2 unknown in the equation (x and y) but only 1 equation. The number of unknowns must be equal to the number of equations (for simultaneous equations)
Simultaneous suggests at least two equations.
