Is point A (1; 2) a solution to this system? 4x-3y = 7 5x + 2y = 26
August 10, 2021 | education
| In order to find out whether a point with coordinates A (1; 2) is a solution to this system:
4x – 3y = 7;
5x + 2y = 26,
we substitute the coordinates of the point A into both equations of the system and perform the calculations. If as a result we get two correct equalities, then we can say that point A is a solution to the system.
x = 1; y = 2.
System of equations:
4 * 1 – 3 * 2 = 7;
5 * 1 + 2 * 2 = 26;
System of equations:
4 – 6 = 7;
5 + 4 = 26;
System:
-2 = 7;
9 = 26.
Point A is not a system solution.
