3x-5(2x+7)=28

3 x - 5 (2 x + 7) = 28

x = - 9

Solution steps

3 x - 5 (2 x + 7) = 28

Expand

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

3 x - 10 x - 35 = 28

Add similar elements:

3 x - 10 x = - 7 x

- 7 x - 35 = 28

Move

35

to the right side

- 7 x = 63

Divide both sides by

- 7

x = - 9

\frac{t}{8} + 6 = 13

x, - 2 x + 3 = 4 y

6 x + 3 + 2 x = 19

f = (\frac{2}{3})^{- 1}

5500 - 45 x = 5100 - 25 x
