b+3= 1/2 (b-4)

b + 3 = \frac{1}{2} (b - 4)

b = - 10

Solution steps

b + 3 = \frac{1}{2} (b - 4)

Expand

\frac{1}{2} (b - 4) : \frac{1}{2} b - 2

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

Move

3

to the right side

b = \frac{1}{2} b - 5

Move

\frac{1}{2} b

to the left side

\frac{1}{2} b = - 5

Multiply both sides by

2

b = - 10

x, 8 x + 5 y = 24

11 x - 2 = 75

34 - 10 x = 6 x + 2

lo g_{10} (2) (x + 2) + lo g_{10} (2) (x - 1) = 2

- \frac{1}{5} x - 25 = - 9
