Answer:
infinite number of solutions
Step-by-step explanation:
Work with the second equation. Subtract 8x from both sides.
- 4y + 8x - 8x = -8x - 12 Collect like terms.
-4y = - 8x - 12 Divide by - 4
-4y/-4 = - 8x/-4 - 12/-4
y = 2x + 3
That is exactly the same line as the first given. There is an infinite number of solutions.
Answer:
Step 1: Add 3y to both sides.
2x−3y+3y=−8+3y
2x=3y−8
Step 2: Divide both sides by 2.
2x

Answer:
x=
3/2 y -4
x+3y=14
x+3y=14
Step 1: Add -3y to both sides.
x+3y+−3y=14+−3y
x=−3y+14
Answer:
x=−3y+14

Answer:
3 units
Step-by-step explanation:
∠A = ∠E (same arc BD)
∠X share
ΔXDA similar to ΔXBE
XE / XA = XB / XD
(3 + DE) / 9 = 2 / 3
9 + 3DE = 18
3DE = 9
DE = 3

Answer:
x = 37
Step-by-step explanation:
Vertically opposite angles are equal
Therefore, 2x + 6 = 80
Subtract 6 from both sides: 2x = 74
Divide both sides by 2: x = 37
