3x-5>7x+12

Solution

3 x - 5 > 7 x + 12

x < - \frac{17}{4}

Solution steps

3 x - 5 > 7 x + 12

Move

5

to the right side

3 x > 7 x + 17

Move

7 x

to the left side

- 4 x > 17

Multiply both sides by

- 1

4 x < - 17

Divide both sides by

4

x < - \frac{17}{4}

\frac{x ^{4} y ^{5}}{x ^{3} y ^{2}}

\frac{\frac{2}{x} - \frac{4}{y}}{\frac{- 5}{y} + \frac{3}{x}}

\frac{25 k - 15}{25 k + 40}

∣ x - 7 ∣ \leq 5

4 x^{2} = 20
