-3=12x-5(2x-7)

- 3 = 12 x - 5 (2 x - 7)

x = - 19

Solution steps

- 3 = 12 x - 5 (2 x - 7)

Switch sides

12 x - 5 (2 x - 7) = - 3

Expand

- 5 (2 x - 7) : - 10 x + 35

12 x - 10 x + 35 = - 3

Add similar elements:

12 x - 10 x = 2 x

2 x + 35 = - 3

Move

35

to the right side

2 x = - 38

Divide both sides by

2

x = - 19

y = 3 \times (- 1)

- \frac{1}{8} = - \frac{1}{3} x - \frac{7}{8}

4 x - 6 = 9 x + 12

5 z + 9 = - 21

7 x = - 2 x + 22
