Answer:
The best first step would be to multiply the second equation by -2
Step-by-step explanation:
The best first step would be to multiply the second equation by -2
then you would have the following
![\ \ \ \ \ \ 4x - 5y = 2 \\-2*(2x)+ (-2)*y = (-2)*3](https://tex.z-dn.net/?f=%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%204x%20-%205y%20%3D%202%20%5C%5C-2%2A%282x%29%2B%20%28-2%29%2Ay%20%3D%20%28-2%29%2A3)
and when you multiply it is easy to eliminate because you will get
![4x - 5y = 2 \\-4x -2y = 6](https://tex.z-dn.net/?f=4x%20-%205y%20%3D%202%20%5C%5C-4x%20-2y%20%3D%206)
and if you sum the equations you get
-7y = 8
so that is a single variable equation which is easier to solve.

Answer:
3z/4
Step-by-step explanation:
Here, we start by calculating the 50% of z
mathematically, that would be 50/100 * z = 50z/100 = z/2
Now we want to calculate the 150% of this.
That would be 150/100 * z/2 = 150z/200 = 3z/4
First what your gonna do is find the slope. So y2-y1/x2-x1 so 17-12/220-120= 5/100 so 1/20. Then you have to put that into slope intercept form. So y=1/20x + b. Then plug in points for x and y. I’ll use 12 and 120. So 12 = 1/20(120)+ b = 12=6+b then subtract 6 from both sides to get b= 6. So your answer is y= 1/20x +6
