(3x-9)/4 =7x+7

\frac{3 x - 9}{4} = 7 x + 7

x = - \frac{37}{25}

Solution steps

\frac{3 x - 9}{4} = 7 x + 7

Multiply both sides by

4

3 x - 9 = 28 x + 28

Move

9

to the right side

3 x = 28 x + 37

Move

28 x

to the left side

- 25 x = 37

Divide both sides by

- 25

x = - \frac{37}{25}

2 k^{2} + 74 k = 0

- 3 x + 6 = 0

\frac{4 x ^{2} - 1}{4 x ^{2} + 8 x + 3} \leq 0

\frac{5 x}{4 - 2 x} \geq \frac{1 + x}{x - 2}
