![x=4\\y=4](https://img.qammunity.org/2020/formulas/mathematics/middle-school/mmtppf0tvus8ocl0e89g4uwt3c9wizfnqc.png)
Step-by-step explanation:
To solve this system of equations using substitution, you must substitute the second equation into the first equation and solve for x, as you can see below:
![4x-2y=8\\4x-2((1)/(2)x+2)=8](https://img.qammunity.org/2020/formulas/mathematics/middle-school/5f3erzjspqvyzw8vxmnqa92lseqzqhtymb.png)
![4x-(2)/(2)x-4=8\\3x-4=8\\3x=8+4\\x(12)/(3)\\x=4](https://img.qammunity.org/2020/formulas/mathematics/middle-school/45gqfek4bw1t01kgyhb9q5cv9okn3o537a.png)
Now you must substitute the value of x into the second equation to find y, then:
![y=(1)/(2)x+2\\\\y=(1)/(2)(4)+2\\\\y=2+2\\y=4](https://img.qammunity.org/2020/formulas/mathematics/middle-school/rohv93qbclrpdqjj9ftsyvus5i4yu1pm0u.png)
