Answer:
y = (-3/2)x + 5
Step-by-step explanation:
Collect like terms
2y = -3x +10
Divide both sides by 2
2y/2 = -3x/2 + 10/2
y = (-3/2)x + 5
Answer:
x = 3.431
Step-by-step explanation:
Given equation is,
By taking log on both the sides of the equation,
(3x - 9)log5 = log8
3x - 9 =
3x - 9 = 1.292
3x = 9 + 1.292
x =
x = 3.4306
x ≈ 3.431
