5x+3(x+4)=28

5 x + 3 (x + 4) = 28

x = 2

Solution steps

5 x + 3 (x + 4) = 28

Expand

3 (x + 4) : 3 x + 12

5 x + 3 x + 12 = 28

Add similar elements:

5 x + 3 x = 8 x

8 x + 12 = 28

Move

12

to the right side

8 x = 16

Divide both sides by

8

x = 2

\frac{x}{8} - 5 = 1, x

\frac{- x}{6} + 1 = \frac{1}{2}

x, f = f (x + 2)

7 x - 10 = 5 x + 6

x, 2 x - 3 y = - 20
