3k+2(5k-3)=7

3 k + 2 (5 k - 3) = 7

k = 1

Solution steps

3 k + 2 (5 k - 3) = 7

Expand

2 (5 k - 3) : 10 k - 6

3 k + 10 k - 6 = 7

Add similar elements:

3 k + 10 k = 13 k

13 k - 6 = 7

Move

6

to the right side

13 k = 13

Divide both sides by

13

k = 1

\frac{3 x - 2}{8} = \frac{x}{2}

- 8 f = - 7 f - 8

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

10 - \frac{3 x + 5}{6} = 3 \frac{11}{12} - \frac{\frac{x}{2}}{4}

x, 6 x + 2 y = 6
