Answer:
Y=9 X=5
Step-by-step explanation:
You can use substitution to solve this problem.
As you see:
X = Y-4
7X-2Y=17
Plug in X to the second equation.
7(Y-4)-2Y=17
Distribute.
7Y-28-2Y=17
Move the 28 with the 17.
7Y-2Y=45
Subtract the Y values.
5Y=45
Y=9
Now find X. Plug in Y to the first equation.
X= 9-4
X= 5
