3+6x=7x+4(-8x-7)

3 + 6 x = 7 x + 4 (- 8 x - 7)

x = - 1

Solution steps

3 + 6 x = 7 x + 4 (- 8 x - 7)

Expand

4 (- 8 x - 7) : - 32 x - 28

3 + 6 x = 7 x - 32 x - 28

Add similar elements:

7 x - 32 x = - 25 x

3 + 6 x = - 25 x - 28

Move

3

to the right side

6 x = - 25 x - 31

Move

25 x

to the left side

31 x = - 31

Divide both sides by

31

x = - 1

\frac{6}{15} = \frac{x}{8}

x, y = f (x - 4) + 2

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

\frac{- ( 3 + 5 )}{4} = \frac{x ( 7 - 8 )}{0.5}

2 x^{2} + 4 x + 8 = 2 (x - h)^{2} + k
