(x+7)(x+3)=(x+8)(x+1)

(x + 7) (x + 3) = (x + 8) (x + 1)

x = - 13

Solution steps

(x + 7) (x + 3) = (x + 8) (x + 1)

Expand

(x + 7) (x + 3) : x^{2} + 10 x + 21

Expand

(x + 8) (x + 1) : x^{2} + 9 x + 8

x^{2} + 10 x + 21 = x^{2} + 9 x + 8

Move

21

to the right side

x^{2} + 10 x = x^{2} + 9 x - 13

Subtract

x^{2} + 9 x

from both sides

x^{2} + 10 x - (x^{2} + 9 x) = x^{2} + 9 x - 13 - (x^{2} + 9 x)

Simplify

x = - 13

11 x + 4 = 3 x - 12

x, - 3 x - 4 y = - 8

4 - 3 x = 17 + 2 x

\frac{x}{16} = 4

4 \frac{1}{2} x = 256
