3x+2(x-1)=6x-9

3 x + 2 (x - 1) = 6 x - 9

x = 7

Solution steps

3 x + 2 (x - 1) = 6 x - 9

Expand

2 (x - 1) : 2 x - 2

3 x + 2 x - 2 = 6 x - 9

Add similar elements:

3 x + 2 x = 5 x

5 x - 2 = 6 x - 9

Move

2

to the right side

5 x = 6 x - 7

Move

6 x

to the left side

- x = - 7

Divide both sides by

- 1

x = 7

13.68 = 0.13 + x

\frac{8 ^{3}}{8 ^{5}}

- 7 x + 5 > 33

y^{2} - 4 y + 2 = 0

x + 10 = 2 x + 4
