3(2+k)-4k=k+16

3 (2 + k) - 4 k = k + 16

k = - 5

Solution steps

3 (2 + k) - 4 k = k + 16

Expand

3 (2 + k) : 6 + 3 k

6 + 3 k - 4 k = k + 16

Add similar elements:

3 k - 4 k = - k

6 - k = k + 16

Move

6

to the right side

- k = k + 10

Move

k

to the left side

- 2 k = 10

Divide both sides by

- 2

k = - 5

x + a = a x + b

3 x + 5 = 7 x - 11

1 - x = x

\frac{2 x}{5} = 8

9 = 10 (x - 2) - 3 x
