x = - \frac{8}{9}

Decimal Notation

x = - 0.88888 \dots

Solution steps

5 x + 4 = - 4 x - 4

Square both sides:

5 x + 4 = - 4 x - 4

5 x + 4 = - 4 x - 4

5 x + 4 = - 4 x - 4 : x = - \frac{8}{9}

x = - \frac{8}{9}

Verify Solutions:

x = - \frac{8}{9}

True

The solution is

x = - \frac{8}{9}

x^{2} - x + 2 x^{2} - x - 5 = 8

1 - 8 x = 5 + 3 x + 9

9 x - 9 - 3 = 0

0 = 3 - \frac{3 x - 1}{2}
