4x-2x^2+9=-2x^2-3

4 x - 2 x^{2} + 9 = - 2 x^{2} - 3

x = - 3

Solution steps

4 x - 2 x^{2} + 9 = - 2 x^{2} - 3

Add

2 x^{2}

to both sides

4 x - 2 x^{2} + 9 + 2 x^{2} = - 2 x^{2} - 3 + 2 x^{2}

Simplify

4 x + 9 = - 3

Move

9

to the right side

4 x = - 12

Divide both sides by

4

x = - 3

- 5 w + 8 (1 + 7 w) = - 8

- 3 + 5 x + 9 = - 2 x + 8 + 7 x

a, 2 a - 5 b = - 19

6 m - 2 m + 14 = 5 (m - 3) + 9

4 + \frac{a}{14} = 5
