Question

desarrolla las siguientes ecuaciones✨​

Answer 1

Respuesta:

$2(x - 9) + 4 = 30$

$2x - 18 + 4 = 30$

$2x - 14 = 30$

$2x = 30 + 14$

$2x = 44$

$x = 44 \div 2$

$x = 22$

2

$2(4x - 7) - 2(x - 4) = 37$

$12x - 21 - 2x + 8 = 37$

$10x - 13 = 37$

$10x = 37 + 13$

$10x = 50$

$x = 50 \div 10$

$x = 5$
