I'm stuck on this problem. Can you help? -4x-9y=1 -x + 2y =-4 WHat is x and y? Two equations in two unknowns. Here is a quick way to solve them -4x - 9y = 1 4x - 8y = 16 (I got that my multiplying both side so the secind equation that you provided by -4) Now add the two ...

**Help;is this correct?**

Graphically, where the services are charging the same rate, the graphs will intersect. A solution of a system of equations in two variables is an ordered pair that makes both equations true.

**algebra**

"write a linear system of equations" This is a linear system of equations. You can use x and y instead of n and b. x = number of blooming annuals y = number of non-blooming annuals 3.20x = value of blooming 1.50y = value of non-blooming x + y = 24 3.20x + 1.50y = 49.60 Then ...
