4=16x-4(5x-7)

4 = 16 x - 4 (5 x - 7)

x = 6

Solution steps

4 = 16 x - 4 (5 x - 7)

Switch sides

16 x - 4 (5 x - 7) = 4

Expand

- 4 (5 x - 7) : - 20 x + 28

16 x - 20 x + 28 = 4

Add similar elements:

16 x - 20 x = - 4 x

- 4 x + 28 = 4

Move

28

to the right side

- 4 x = - 24

Divide both sides by

- 4

x = 6

y, 4 - y = x

y, x = \frac{yz}{6}

\frac{x}{4} - \frac{x}{5} = 2

- 8 + 0.75 z = 12 - 0.25 z

- 32 + 10 b = - 22 - 22
