Find the solution of this system of equations -2x equals 2 plus 1y -6x-y equals -2?
Assuming that you are giving two separate equations:
Your answer is x = 1 & y = -4
Given Equations
-2x = 2 + y
-6x - y = -2
Derived Equations
3 * (2+y) - y = -2
6 + 3y - y = -2
6 + 2y = -2
2y = -8
y = -4
-2x = 2 + (-4)
-2x = -2
x = 1
Checking Answers
-2 * (1) = 2 + (-4)
-2 = -2
-6 * (1) - (-4) = -2
-6 + 4 = -2
-2 = -2

How do you check a solution to a system of equations?
Put the values that you find (as the solution) back into one (or more) of the original equations and evaluate them. If they remain true then the solution checks out. If one equation does not contain all the variables involved in the system, you may have to repeat with another of the original equations.
When solving a system of equations by elimination you find what?
You find a solution set. Depending on whether the equations are linear or otherwise, consistent or not, the solution set may consist of none, one, several or infinitely many possible solutions to the system.

When we look for a solution for a system of equations or inequalities are we looking into an AND situation or an OR situation?
Unless otherwise stated, the "AND" case is normally assumed, i.e., you have to find a solution that satisfies ALL equations.
What is the solution of the system of equation graphed y equals -2 plus 5 y equals x-5?
To find the solution of the system of equations ( y = -2 + 5 ) and ( y = x - 5 ), we first simplify the first equation to ( y = 3 ). Next, we set ( 3 = x - 5 ) from the second equation and solve for ( x ), yielding ( x = 8 ). Therefore, the solution to the system is the point ( (8, 3) ).
What is the solution of x plus y equals 5?
You have two unknown variables, x and y. You therefore need at least two independent equations to find a solution.
If two equation are graphed how can you find the solution?
To find the solution of two equations graphed on a coordinate plane, look for the point where the two lines intersect. This point represents the values of the variables that satisfy both equations simultaneously. The coordinates of this intersection point are the solution to the system of equations. If the lines are parallel, there is no solution; if they are the same line, there are infinitely many solutions.
How do you find the solution to the system of equations on ti- 89 calculator?
