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.)
The solution is: x = 1 and y = -1
It is (-1, 3).
1). y = 12). y = -4x3). y = -12xA "solution" is a pair of numbers ... one for 'x' and one for 'y' ... that makes the statements true.There is no solution for the group of all three equations.The solution for #1 and #2 taken together is (-1/4 , 1).The solution for #1 and #3 taken together is (-1/12 , 1).The solution for #2 and #3 taken together is (0, 0).
y=sin x y=cos x cos x sin x = cos^2 x sin x = 1-sin^2 x sin x -1 + sin^2 x = 0 sin^2 x + sin x -1 = 0 Let y=sin x y^2+y-1 = 0 This equation is of form ay^2+by+c=0 a = 1 b = 1 c = -1 y=[-b+/-sqrt(b^2-4ac)]/2a] y=[-1 +/-sqrt(1^2-4(1)(-1)]/(2)(1) discriminant is b^2-4ac =5 y=[-1 +√(5)] / 2 y=[-1 -√(5)] / 2 sin x = [-1 +√(5)] / 2 x = sin^-1 [-1 +√(5)] / 2] = 0.6662394 radians x = sin^-1 [-1 -√(5)] / 2] = sin^-1 (-1.618) -- has no solution When x = 0.6662394 radians, sin x and cos x times cos x are equal.
Y=a(x-h)+k is the vertex formula. Since the vertex is at (-2,-3) this parabola has the equation: y=a(x+2)^2-3 We can plug in x=-1 but we really need to know a, to solve for y. ( we can solve it, but we will have an a in the solution)
The solution is: x = 1 and y = -1
Yes, since (1,2) satisfies y = x + 1 y = (1) + 1 y = 2 and 2 = 2
If by that you mean x= 1 and y= 2 then yes (1,2) is a solution
There is one solution for x and one solution for y. The solution is: x = -1 ; y = 2
In the equations Y=X-1 and Y=-X+1, the solution is (1,0)
The mathematical symbols did not appear so I am assuming that your question is if the point (-1,-1) is a solution of y = 3x + 2, in that case, substitute -1 for y and -1 for x and you get -1 = 3(-1) + 2 or -1 = -3 + 2 or -1 = -1 Thus if I assumed the question correctly, then -1,-1 is a solution to y = 3x + 2
y = x + 1
y = 3, x = 1 y = 4, x = 2 Anything where y is two greater than x will work.

There are infinitely many "solutions". In the Cartesian plane, the coordinates of any point on the line defined by y = x + 2 is a solution. Thus, any ordered pair, (x, x+2) is a solution.
Yes if x=2 and y=2, then x=y
x + 2y = 3 x + y = 1 Subtract second equation from the first to give: 0x + 1y = 2 ie y = 2 Substitute this value of y in the second equation: x + 2 = 1 so that x = -1 The solution is x = -1, y = 2
