WebYou can multiply both equations by a number to get one of the x or y absolute values the same, multiply the top equation by 2, to get 8x-6y=16, and the second equation by -3 to get -15x+6y=33, then add the equations to get -7x=49, so x is equal to -7. Plug in -7 for x to solve for y which would be -12. Hope this helps. WebRepresenting a linear system with matrices. A system of equations can be represented by an augmented matrix. In an augmented matrix, each row represents one equation in the system and each column represents a variable or the constant terms. In this way, we can see that augmented matrices are a shorthand way of writing systems of equations. ore house hours
