Answer:
x=7
y=10.5
Step-by-step explanation:
1. You can apply the method of substitution, as you can see below:
- Substitute
into the other equation and solve fo x:
![x-2(2x-3.5)=-14\\x-4x+7=-14\\x=7](https://tex.z-dn.net/?f=x-2%282x-3.5%29%3D-14%5C%5Cx-4x%2B7%3D-14%5C%5Cx%3D7)
- Substitute the value of x obtain into the first equation, then the value of y is:
![y=2(7)-3.5\\y=10.5](https://tex.z-dn.net/?f=y%3D2%287%29-3.5%5C%5Cy%3D10.5)
The answer is f open circle means < and closed means _< just under the sign tho
