Question

A) 32x+5=25-3x
B) 43x-3=22+7x
C) 25x=25
D) 3 2x+7=45
E) 7x=32-5x
F) 72x+48=45=23x

Answer 1

$a) \: 32x + 5 = 25 - 3x \\ 32x + 3x = 25 - 5 \\ 35x = 20 \\ 35x = \frac{20}{35} simplifica \div 5 \\ x = \frac{4}{7}$

$b) \: 43x - 3 = 22 + 7x \\ 43x - 7x = 22 + 3 \\ 36x = 25 \\ x = \frac{25}{36}$

$c) \: 25x = 25 \\ x = \frac{25}{25 } \\ \\ x = 1$

d) está incompleta

$e) \: 7x = 32 - 5x \\ 7x + 5x = 32 \\ 12x = 32 \\ x = \frac{32}{12} ( \div 4 )\\ \\ x = \frac{8}{3}$

$f) \: 72x + 48 = 45 - 23x \\ 72x + 23x = 45 - 48 \\ 95x = - 3 \\ x = \frac{ - 3}{95}$
