-3x-4x=15+x/2

- 3 x - 4 x = 15 + \frac{x}{2}

x = - 2

Solution steps

- 3 x - 4 x = 15 + \frac{x}{2}

Add similar elements:

- 3 x - 4 x = - 7 x

- 7 x = 15 + \frac{x}{2}

Multiply both sides by

2

- 14 x = 30 + x

Move

x

to the left side

- 15 x = 30

Divide both sides by

- 15

x = - 2

0 = x^{2} + x - 1

- 7 x < 42

(x + 2)^{2} = 4

2 a^{2} + 11 a + 5

\frac{2 ^{0}}{( 2 ^{- 2} x ^{\frac{1}{2}} y ^{- 2} ) ^{3}}
