Answer:
infinite number of solutions
Step-by-step explanation:
y = 4x - 11 → (1)
4x - y = 11 → (2)
Substitute y = 4x - 11 into (2)
4x - (4x - 11) = 11 ← distribute parenthesis on left side
4x - 4x + 11 = 11 ( subtract 11 from both sides )
0 = 0 ← true statement
This indicates the system has an infinite number of solutions
