(x+5)(x+7)=(x+5)x

(x + 5) (x + 7) = (x + 5) x

x = - 5

Solution steps

(x + 5) (x + 7) = (x + 5) x

Expand

(x + 5) (x + 7) : x^{2} + 12 x + 35

Expand

(x + 5) x : x^{2} + 5 x

x^{2} + 12 x + 35 = x^{2} + 5 x

Move

35

to the right side

x^{2} + 12 x = x^{2} + 5 x - 35

Subtract

x^{2} + 5 x

from both sides

x^{2} + 12 x - (x^{2} + 5 x) = x^{2} + 5 x - 35 - (x^{2} + 5 x)

Simplify

7 x = - 35

Divide both sides by

7

x = - 5

3 y + 6 = - 30 + 2 y

- 2 + \frac{3}{4} j + \frac{1}{2} j = 2 j

\frac{0.3 d - 1}{3 \frac{1}{3}} = \frac{0.84}{\frac{7}{15}}

x, 3 x - y = - 2

x, 3 x - 2 y + 5 = 4 x - 7 y - 3
