5x+2(x+1)=23

5 x + 2 (x + 1) = 23

x = 3

Solution steps

5 x + 2 (x + 1) = 23

Expand

2 (x + 1) : 2 x + 2

5 x + 2 x + 2 = 23

Add similar elements:

5 x + 2 x = 7 x

7 x + 2 = 23

Move

2

to the right side

7 x = 21

Divide both sides by

7

x = 3

3 - 5

2 x + 4 - x = 4 x - 5

\frac{- 50}{5}

2 x - 4 \geq 2

81 - 45 x + 4 x^{2} = 0
