3a-5(a-2)=34

3 a - 5 (a - 2) = 34

a = - 12

Solution steps

3 a - 5 (a - 2) = 34

Expand

- 5 (a - 2) : - 5 a + 10

3 a - 5 a + 10 = 34

Add similar elements:

3 a - 5 a = - 2 a

- 2 a + 10 = 34

to the right side

- 2 a = 24

Divide both sides by

- 2

a = - 12

2 (4 x - 3) = 4 x - 78

5 h - 7 = 2 (h + 1)

x, 7 x + y = 2

x, 7 x + y = 9

4 x - \frac{x}{2} - 3 = \frac{1}{2}
