13+2k=3k+4(k-3)

13 + 2 k = 3 k + 4 (k - 3)

k = 5

Solution steps

13 + 2 k = 3 k + 4 (k - 3)

Expand

4 (k - 3) : 4 k - 12

13 + 2 k = 3 k + 4 k - 12

Add similar elements:

3 k + 4 k = 7 k

13 + 2 k = 7 k - 12

Move

13

to the right side

2 k = 7 k - 25

Move

7 k

to the left side

- 5 k = - 25

Divide both sides by

- 5

k = 5

4 x^{2} + 6 x + 2 = 0

3 b (b - 4) + 6 (b - 8)

3 a^{2} + 11 a - 20

\frac{1 + 2 i}{i}

(3 m)^{2} + (2 m + 4)^{2} = (5 m)^{2}
