x+y=-8 2x-y=4 y=-x-8 2x+x+8=4 3x=-4 x=-4/3 -4/3 + y= -8 y = -8 + 4/3 y= -6 2/3
I understand the equation to be y = -3x - 2 and the point to be (5,1). I substitute 1 for each appearance of y and 5 for each appearance of x: 1 = -3(5) - 2 = -15 - 2 = -17, which is not a true statement. Therefore, that is not a solution. To get a solution, set x=1, and calculate y by substituting this value (1) for x wherever it appears: y = -3(1) - 2 = -3 - 2 = -5. Therefore, (-5,1) is a solution. (I suspect that this is what you meant to put in the question.)
If the expression is (x - y)2, the solution is (7 - -2)2 = (7+2)2 = 92 = 81. If the expression is x - y2, the solution is 7 - (-2)2 = 7 - 4 = 3.

The answer to Y x plus 5 Y 6 is Y(x+5Y5).One possible solution to y x plus 5 y 6 is Y(x+5Y5).
Because this question has more than one variable( x and y) the solution is impossible to find (a number). To make it easier to find x or y, x = a - y + 3 y = 3 - x - a where a = y - x + 3
y=x y=6-x Set the two equations equal to each other to yield a solution: x=6-x 2x=6 x=3 x=3 will satisfy both equations, that is plugging in x=3 will give the same value for y y=(3)=3 y=6-(3)=3
If you mean: y+x = 3 then the solutions are (0, 3) and (3, 0)
-5x=3+y x=-1/5y-3/5
x = y = 3
y = x - 1 y - x = 3 y = x - 1 y = x + 3 Since both equations represent straight lines that have equal slopes, 1, then the lines are parallel to each other. That is that the lines do not intersect, and the system of the equations does not have a solution.

x = 0 & y = -3
The solution to the equation 0.81y + 3x is 3(0.27y + x).
X+Y=2 There are a variety of answers to this equation since there are two variables, x and y. For example, X can be .5 while Y is 1.5. Or, X can be -3 while Y can be 5. There is no solution to this problem.
x = -3, y = 7
x = 1 and y = 2
