Solution steps

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

Multiply both sides by

4

28 x + 28 = 3 x - 9

Move

28

to the right side

28 x = 3 x - 37

Move

3 x

to the left side

25 x = - 37

Divide both sides by

x = - \frac{37}{25}

1 2^{2} + 1 2^{2} = x^{2}

(7 - 2)^{2}

(7 + 2) (7 - 2)

- 3 \leq 2 x + 5 < 7
