2x+5x-7=2(2x-1)-1

2 x + 5 x - 7 = 2 (2 x - 1) - 1

x = \frac{4}{3}

Decimal Notation

x = 1.33333 \dots

Solution steps

2 x + 5 x - 7 = 2 (2 x - 1) - 1

Add similar elements:

2 x + 5 x = 7 x

7 x - 7 = 2 (2 x - 1) - 1

Expand

2 (2 x - 1) - 1 : 4 x - 3

7 x - 7 = 4 x - 3

Move

7

to the right side

7 x = 4 x + 4

Move

4 x

to the left side

3 x = 4

Divide both sides by

3

x = \frac{4}{3}

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

x^{12} + 2 x^{6} + 1

5 (u + 1) - u = 4 (u - 1) + 9

x^{2} - 7 x + 10 > 0

12 x^{2} + 60 x + 75 = 0
