Evaluate when w = -1, x = -2, y = -3, z = -4 z/x + -8y + 2w - wxyz

-7

Step-by-step explanation:

w = -1, x = -2, y = -3, z = -4

z/x + -8y + 2w - wxyz

(-4)/(-2) + (-8)(-2)  + (2)(-1) - (-1)(-2)(-3)(-4)

2+ 16 + (-1) - (24)

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
