i have no idea what im doing. i missed a day and now my teacher wont tell me how to do this
will you please help me solve the following system of equations. 1. 3x - 2y = 4 2x - 5y = 21 2. 3x + y = 7 ...
x-3y+4z=13 2x+y+z=-2 -2x+3y-3z=-10
5/4x - 4/3y + 5/4z = 6 5/16x + 5/4y - 4/16z = -4 3/4x - y +3/4z = 6
Did I solve these correctly? 1. 5x - 2y = -24 - 4y = -48 - 10x = 5x - 2y = -24 ...
did I solve this correctly? 3x + y = 7 3x + y = 10 (mulitply by -1) = -1(3x + y) = -1(10) = ...
