X - y= -1
X-3y=-13
How could you check to see if the point (5, 6) is the solution to the Linear System of equations?
* Substitute 6 in for x and 5 in for y in one of the equations to see if the equation is true.
* Substitute 6 in for x and 5 in for y in both of the equations to see if both equations are true.
* Substitute 5 in for x and 6 in for y in both of the equations to see if both equations are true.
To check if the point (5, 6) is the solution to the linear system of equations X - y = -1 and X - 3y = -13, we can substitute the values of x = 5 and y = 6 into both equations and see if they are true.
1. Substitute x = 5 and y = 6 into the first equation:
5 - 6 = -1
-1 = -1
The first equation is true when x = 5 and y = 6.
2. Substitute x = 5 and y = 6 into the second equation:
5 - 3(6) = -13
5 - 18 = -13
-13 = -13
The second equation is also true when x = 5 and y = 6.
Since both equations are true when x = 5 and y = 6, the point (5, 6) is indeed the solution to the given linear system of equations.
