1, Simplify 7d+d-4d-77d+d−4d−7 to 4d-74d−7

4d-7=5d4d−7=5d

2.Subtract 4d4d from both sides
-7=5d-4d−7=5d−4d

3. Simplify 5d-4d5d−4d to dd
-7=d−7=d

4. Switch sides
d=-7d=−7
5. so your answer would be -7

finlep [7]

Answer:

Two

Step-by-step explanation:

x² + 4 = 4x + 1

x² - 4x + 3 = 0

x² - 3x - x + 3 = 0

x(x - 3) - (x - 3) = 0

(x - 3)(x - 1) = 0

x = 1, 3

y = 4(1) + 1 = 5

y = 4(3) + 1 = 13

Two solutions: (1,5) (3,13)
