Answer: (9,8)
Step-by-step explanation:
let 2x - y = 10 be [a] & y = x − 1 be [b]
First, lets substitute [b] into [a] and solve for x
2x - ( x - 1) = 10
2x - x = 10 - 1
x = 9
Now, since x = 9, we can substitute for x in [b]
⇒ y = 9 - 1
y = 8
∴ the solution for the system of equations is x = 9, y = 8 OR (9, 8)
