Question

Ayudaaa! Doy coronita

Answer 1

Respuesta:

$1)2x + 16 = 8400 \\ 2x = 8400 - 16 \\ 2x = 8384 \\ x = \frac{8384}{2} \\ x = 4192$

$2)3x - 15 = - 1710 \\ 3x = - 1710 + 15 \\ 3x = - 1695 \\ x = - \frac{1695}{3} \\ x = - 565$

$3) - 9y + 18 = 7110 \\ 18 - 7110 = 9y \\ - 7092 = 9y \\ - \frac{7092}{9} = y \\ - 788 = y$

$4) - 8x = - 4860 - 2x \\ 4860 = - 2x + 8x \\ 4860 = 6x \\ \frac{4860}{6} = x \\ 810 = x$

$5)7y = 5880 + 2y \\ 7y - 2y = 5880 \\ 5y = 5880 \\ y = \frac{5880}{5} \\ y = 1176$

$6) \frac{x}{6} + 12 = 408 \\ 6( \frac{x}{6} + 12 ) = 6 \times 408 \\ x + 72 = 2448 \\ x = 2448 - 72 \\ x = 2376$

$7) \frac{x}{5} - 10 = - 980 \\ 5( \frac{x}{5} - 10 ) = - 980 \times 5 \\ x - 50 = - 4900 \\ x = - 4900 + 50 \\ x = - 4850$

$8)x + 18 = 846 - 3x \\ x + 3x = 846 - 18 \\ 4x = 828 \\ x = \frac{828}{4} \\ x = 207$

$9)x - 17 = - 507 - 6x \\ x + 6x = - 507 + 17 \\ 7x = - 490 \\ x = - \frac{490}{7} \\ x = - 70$

$10)y - 25 = 389 - y \\ y + y = 389 + 25 \\ 2y = 414 \\ y = \frac{414}{2} \\ y = 207$
