I’m sorry this is messy but I hope this is right!! <3
13x+6y = -30................y = -5 -13x/6
x−2y=−4...................... y = x/2 +2 <span>
If we graph both lines we can get the solution of the system (point of intersection)
The best estimate is (x,y) = (-2.625, 0.688)</span>

Let the amount invested at 4% be = x
Let the amount invested at 3% be = y
Given is:
or
.... (1)
As, total income for the two investments is $194, so equation is:
....(2)
Putting value of x from (1) in (2)
![0.04(5200-y)+0.03y=194](https://tex.z-dn.net/?f=0.04%285200-y%29%2B0.03y%3D194)
![208-0.04y+0.03y=194](https://tex.z-dn.net/?f=208-0.04y%2B0.03y%3D194)
![0.01y=14](https://tex.z-dn.net/?f=0.01y%3D14)
![y=1400](https://tex.z-dn.net/?f=y%3D1400)
And x=5200-y
![x=5200-1400=3800](https://tex.z-dn.net/?f=x%3D5200-1400%3D3800)
Hence, money invested at 4% is $3800 and money invested at 3% is $1400
Answer:
Z = 8.8 Y = - 42
Step-by-step explanation:
Y = 2 - 5Z
Y = 5 - 47
2 - 5Z = 5 - 47
- 5Z = - 44
5Z = 44
Z = 8.8
Y = 2 - 5 (8.8)
Y = 2 - 44
Y = - 41
Y = 5 - 47
Y = - 42
