Substitute this equation 2x-y=17 & x-y=10

(7,-3)

Step-by-step explanation:

so first you would solve the equation, then you would substitute the value of y then solve the equation then substitute the value of x  (x=7)and solve the equation a possible solution is -3, then checking the solution to make sure it's what you got (7,-3), then you would simplify then the ordered pair is a solution and your solution is (x,y) (7,-3)
