Question

exponent and power class 8​

Answer 1

Answer:

$\frac{x + 7}{x + 6} = \frac{x + 5}{x + 2} \\ (x + 7 )(x + 2) = (x + 5)(x + 6) \\ ( {x}^{2} + 2x + 7x + 14) = {x}^{2} + 6x + 5x + 30 \\ 2x + 7x + 14 = 6x + 5x + 30 \\ 9x + 14 = 11x + 30 \\ 11x -9x = 30 - 14 \\ 2x = 16 \\ x = \frac{16}{2} \\ x = 8$
