-5x - 15 > 10 + 20x / + 15
-5x > 25 + 20x / - 20x
-25x > 25 / ÷ ( -25 )
x < - 1

So isolate x on one side

-5x-15>10+20x
add 5x to both sides
-15>10+25x
subtract 10 from both sides
-25>25x
divid eboth sides by 25
-1>x
so anything smaller than -1 so exg -2,-2355,-45

Question 8b , thanks
marta [7]

Answer:

Step-by-step explanation:

a = \frac{2b+1}{3b-1}

b = 2/3

2b + 1 = 2*\frac{2}{3}+1\\\\=\frac{4}{3}+1\\\\=\frac{4}{3}+\frac{3}{3}\\\\=\frac{7}{3}\\\\3b-1 = 3*\frac{2}{3}-1\\\\=2- 1 = 1\\\\\\

a = \frac{2b+1}{3b-1}\\\\a=\frac{\frac{7}{3}}{1}\\\\=\frac{7}{3}\\\\

a = 7/3

b)

\frac{2b+1}{3b-1}=a\\\\

Cross multiply,

2b + 1 = a*(3b - 1)

2b + 1 = a*3b - 3*a

2b + 1 = 3ab- 3a

2b = 3ab - 3a - 1

2b - 3ab = -3a  - 1

b(2 - 3a) = -3a - 1

b =\frac{-3a - 1}{2 - 3a}
