75=5x-3(-3x+3)

75 = 5 x - 3 (- 3 x + 3)

x = 6

Solution steps

75 = 5 x - 3 (- 3 x + 3)

Switch sides

5 x - 3 (- 3 x + 3) = 75

Expand

- 3 (- 3 x + 3) : 9 x - 9

5 x + 9 x - 9 = 75

Add similar elements:

5 x + 9 x = 14 x

14 x - 9 = 75

Move

9

to the right side

14 x = 84

Divide both sides by

14

x = 6

- 3 x + 3 = 5 x + 6 + 0

7 - 2 + x + 3 x = 25

7.34 x - 20 = 0.34 x + 10

3 x = \frac{6}{7}

3 (x - 7) + 5 = 2 x + 4
