Solving a system of two equations
WebBelow we will show that the above system of equations is consistent. Equivalently, this means that the above vector equation has a solution. In other words, there is a linear combination of (1,2,6) and (− 1,2, − 1) that equals (8,16,3). We can visualize the last statement geometrically. Therefore, the following figure gives a picture of a ... WebSolve the system. eliminate x, multiply both sides of equation (4) by -2 and both sides of equation (S) by 3 to get equations (6) and (7). Although this new system is not the same …
