Which equation is an xy-equation for the parametric equations x equals -3t plus 4 and y equals t plus 1 where 1 t 4?
You're looking to combine these two equations into one that uses only the terms x and y, right? In that case, we can take either of those equations, solve it for t, and plug it's results in place of t in the other equation:
x = -3t + 4
y = t + 1
y - 1 = t
x = -3(y - 1) + 4
x = -3y + 3 + 4
x = 7 - 3y
You can of course solve this for y as well:
-3y = x - 7
y = (7 - x) / 3

Answer this equations x plus 42y equals 4?
Solving equations in two unknowns requires two independent equations. Since you have only one equation there is no solution.
Is 3x 5 an equation?
Not until it equals something. Equations have equals signs.
What is the equation that always equals 2?
well there are many equations actually.
Does an equation have an equal sign?
yes. equations have an equals signs and expressions don't
What are the values called at which the equation equals zero?
They are called the solutions or roots of the equations.

Solving equations in two unknowns requires two independent equations. Since you have only one equation there is no solution.
Simultaneous equation 2x-2y equals 10?
Simultaneous suggests at least two equations.
Y plus 4 equals 4x-2?
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)
