7(3x+9)=11-(x+3)

7 (3 x + 9) = 11 - (x + 3)

x = - \frac{5}{2}

Decimal Notation

x = - 2.5

Solution steps

7 (3 x + 9) = 11 - (x + 3)

Expand

7 (3 x + 9) : 21 x + 63

Expand

11 - (x + 3) : - x + 8

21 x + 63 = - x + 8

Move

63

to the right side

21 x = - x - 55

Move

x

to the left side

22 x = - 55

Divide both sides by

22

x = - \frac{5}{2}

- \frac{3}{4 ^{2}}

5 - 8 w \leq 11 - 6 w

4 x^{2} + 14 x = 5

(x - 3)^{2} (2 x + 1)^{3} + (x - 3)^{3} (2 x + 1)^{2}

4 x + 5 < x^{2}
