Resposta:

Item a)

$5x+7=4x+10\\5x-4x=10-7\\x=4$

Item b)

$5x-3=2x+9\\5x-2x=9+3\\3x=12\\x=4$

Explicação passo-a-passo:

Answer 2

$a)5x + 7 = 4x + 10$

$5x - 4x = 10 - 7$

$x = 3$

______________________________________

$b)5x - 3 + x = 2x + 9$

$5x + x - 2x = 9 + 3$

$4x = 12$

$x = \frac{12}{4}$

$x = 3$
