-4x+3(2x-5)=31

- 4 x + 3 (2 x - 5) = 31

x = 23

Solution steps

- 4 x + 3 (2 x - 5) = 31

Expand

3 (2 x - 5) : 6 x - 15

- 4 x + 6 x - 15 = 31

Add similar elements:

- 4 x + 6 x = 2 x

2 x - 15 = 31

Move

15

to the right side

2 x = 46

Divide both sides by

2

x = 23

3 - \frac{1}{5} x = - 7

2 (- 2 x - 4) = - 4 x - 8

5 x - 6 = 8 - 2 x

y + 4 = - 36

16 = \frac{x}{11}
