Answer:
x = 2
y = 7
Step-by-step explanation:
ON = LM
therefore
12x - 5 = 4x + 11
+5 +5
12x = 4x + 16
-4x -4x
8x = 16
/8 /8
x = 2
NM = OL
therefore
x + 7 = 2y - 5
(2) + 7 = 2y - 5
9 = 2y - 5
+5 +5
14 = 2y
/2 /2
7 = y
Answer:
(x, y) = (- 3, 4)
Step-by-step explanation:
Given the 2 equations
5x + 2y = - 7 → (1)
4x - y = - 16 → (2)
multiply all terms in (2) by 2
8x - 2y = - 32 → (3)
Add (1) and (3) term by term
(5x + 8x) + (2y - 2y) = (- 7 - 32)
13x = - 39 ( divide both sides by 13 )
x = - 3
Substitute x = - 3 into either (1) or (2) and solve for y
substituting in (1) gives
(5 × - 3) + 2y = - 7
- 15 + 2y = - 7 ( add 15 to both sides )
2y = 8 ( divide both sides by 2 )
y = 4
solution is (- 3, 4 )
