Answer:
(3, 6 )
Step-by-step explanation:
Given the 2 equations
x = y - 3 → (1)
2x + y = 12 → (2)
In equation (1) subtract y from both sides
x - y = - 3 → (3)
Add (2) and (3) term by term to eliminate y
(2x + x) + (y - y) = (12 - 3), that is
3x = 9 ( divide both sides by 3 )
x = 3
Substitute x = 3 into (2) and solve for y
(2 × 3) + y = 12
6 + y = 12 ( subtract 6 from both sides )
y = 6
Solution is (3, 6 )
2 over 3 you're welcome :)
Answer:
(6,2)
Step-by-step explanation:
Diagonals have the same midpoint
(6-1)/2, (-1+2)/2 = (-1+x)/2, (-1+y)/2
