Given that abcd is a rhombus, what is the value of x?

Using elimination, what is -4x+2y=-12 4x+8y=-24

The input to the function is x and the output is y. write the function such that x can be a vector (use element-by-element operations). a) use the function to calculate y(-1.5) and y(5). b) use the function to make a plot of the function y(x) for -2 ≤ x ≤ 6.
