Answer:
Solve one of the following equations for x or y and then substitute the answer to that equation into the second equation.
Step-by-step explanation:
Given the system of equations:
[tex]x-y=7[/tex]
[tex]2x-y=17[/tex]
You could solve either one of the given equations but for this question we will solve the first equation.
[tex]x-y=7[/tex]
Solve for x
Subtract y
[tex]x=5-y[/tex]
Now substitute the answer for the first equation into the second equation.
Hope this helps.
