If "equations-" is intended to be "equations", the answer is y = -2.
If the first equation is meant to start with -3x, the answer is y = 0.2
{-1,-2}
(10, 2)
It's an inconsistent pair of equations, for which there is no solution.
y = 0 and x = 8.
There is no solution for those equations because the lines are parallel so, they never touch.
x = y = 3
{-1,-2}
There are two solutions and they are: x = -1 and y = 3
No solution

When (the graph of the equations) the two lines intersect. The equations will tell you what the slopes of the lines are, just look at them. If they are different, then the equations have a unique solution..
Yes.
-1
No.
The graphs of those two equations are straight lines, each of which passes through the origin. The origin is the common solution ... the point (0, 0).
A possible first step in eliminating a variable in the system of equations (4x + 5y = -23) and (3x + 10y = -14) is to manipulate the equations to align the coefficients of one of the variables. For instance, you can multiply the first equation by 2 to obtain (8x + 10y = -46). This will allow you to eliminate the (y) variable by subtracting the second equation from the modified first equation.
