Answer:
B and A
Step-by-step explanation:
The diagonals of a rhombus bisect each other at right angles, thus
(3)
y = x + 3 → (1)
3x + 2 = y + 1 → (2)
Substitute y = x + 3 into (2)
3x + 2 = x + 3 + 1
3x + 2 = x + 4 ( subtract x from both sides )
2x + 2 = 4 ( subtract 2 from both sides )
2x = 2 ( divide both sides by 2 )
x = 1 → B
(4)
Substitute x = 1 into (1)
y = 1 + 3 = 4 → A
