3x+15-9=2(x+2)

3 x + 15 - 9 = 2 (x + 2)

x = - 2

Solution steps

3 x + 15 - 9 = 2 (x + 2)

Add/Subtract the numbers:

15 - 9 = 6

3 x + 6 = 2 (x + 2)

Expand

2 (x + 2) : 2 x + 4

3 x + 6 = 2 x + 4

Move

6

to the right side

3 x = 2 x - 2

Move

2 x

to the left side

x = - 2

\frac{3 x - 1}{5} - \frac{x - 2}{2} = x + 4

\frac{3 x}{4} = 9

2^{6}

\frac{- 7 n ^{2}}{- 14 n ^{2} - 35 n}

\frac{3}{8} x - \frac{1}{5} x + 10 = \frac{3}{10} x
