(x+7)(x-5)=(x-4)(x+4)

(x + 7) (x - 5) = (x - 4) (x + 4)

x = \frac{19}{2}

Decimal Notation

x = 9.5

Solution steps

(x + 7) (x - 5) = (x - 4) (x + 4)

Expand

(x + 7) (x - 5) : x^{2} + 2 x - 35

Expand

(x - 4) (x + 4) : x^{2} - 16

x^{2} + 2 x - 35 = x^{2} - 16

Move

35

to the right side

x^{2} + 2 x = x^{2} + 19

Move

x^{2}

to the left side

2 x = 19

Divide both sides by

2

x = \frac{19}{2}

x, y - 1 = \frac{1}{2} (x - 2)

x, 2 x = y + 4

x, 2 x - 12 y = 24

40000 = 6000 \cdot h + 20000 \cdot (4 - 1.5 - h)

E = 2 g h
