-2x^2+x+7=-x^2+5x+(-2-x^2)

- 2 x^{2} + x + 7 = - x^{2} + 5 x + (- 2 - x^{2})

x = \frac{9}{4}

Decimal

x = 2.25

Solution steps

- 2 x^{2} + x + 7 = - x^{2} + 5 x + (- 2 - x^{2})

Remove parentheses:

(- a) = - a

- 2 x^{2} + x + 7 = - x^{2} + 5 x - 2 - x^{2}

Group like terms

- 2 x^{2} + x + 7 = - x^{2} - x^{2} + 5 x - 2

Add similar elements:

- x^{2} - x^{2} = - 2 x^{2}

- 2 x^{2} + x + 7 = - 2 x^{2} + 5 x - 2

Move

7

to the right side

- 2 x^{2} + x = - 2 x^{2} + 5 x - 9

Subtract

- 2 x^{2} + 5 x

from both sides

- 2 x^{2} + x - (- 2 x^{2} + 5 x) = - 2 x^{2} + 5 x - 9 - (- 2 x^{2} + 5 x)

Simplify

- 4 x = - 9

Divide both sides by

- 4

x = \frac{9}{4}

10 + 125 c = 20

5 + 11 x = 1 + x

y, - 2 x + 4 y = - 8

10 - 4 (x + 9) = 14

b, a = b (c - d)
