Study Notes

Algebra (Addition Method)

The system of equations 2x + 3y = 9 and -2x + 2y = 6 gives a y-coordinate solution of 3.
For the equations 5x + y = 6 and 5x + 3y = -4, the y-coordinate solution is -5.
The solution for x - y = 4 and x + y = 8 yields an x-coordinate of 2.
The equations x + y = k and x - y = k produce a solution of (k, 0).
The x-coordinate for the system represented by 2x + y = -2 and x + y = 5 is -7.
Subtracting the second equation 3x + 2y = -5 from the first 3x - 4y = 7 results in -6y = -12.
In the equations 2x + 3y = 6 and 5x + 2y = 4, a possible elimination result could be 19y = 22.
The system 3x - 4y = 6 and 6x - 8y = 10 has no solutions, indicating parallel lines.
In the equations 3x + 5y = 78 and 2x - y = 0, the point of intersection has an x-coordinate of 6.
The solution to the equations 7x - 3y = 4 and 2x - 4y = 1 results in the coordinates (13/22, 1/22).
For the line system x + 5y = -2 and 2x + y = 5, the y-coordinate of the intersection is -1.
The equations 7x - 3y = 4 and 2x - 4y = 1 do not equate to the system represented by 28x - 12y = 16 and -6x + 12y = -3.
To achieve an x-coordinate of 3 in an unknown system, the value of b must be 7.
