x^2+5x-2(x^2+3)=-x^2-3x+11

x^{2} + 5 x - 2 (x^{2} + 3) = - x^{2} - 3 x + 11

x = \frac{17}{8}

Decimal

x = 2.125

Solution steps

x^{2} + 5 x - 2 (x^{2} + 3) = - x^{2} - 3 x + 11

Expand

x^{2} + 5 x - 2 (x^{2} + 3) : - x^{2} + 5 x - 6

- x^{2} + 5 x - 6 = - x^{2} - 3 x + 11

Move

6

to the right side

- x^{2} + 5 x = - x^{2} - 3 x + 17

Subtract

- x^{2} - 3 x

from both sides

- x^{2} + 5 x - (- x^{2} - 3 x) = - x^{2} - 3 x + 17 - (- x^{2} - 3 x)

Simplify

8 x = 17

Divide both sides by

8

x = \frac{17}{8}

y, 2 x = 5 - 3 y

20 - x = - 1

x, 5 = x - 21 + q

2^{2} + 3^{2} = 13^{2}

2 x + 12 = 30
