Question

/2+x=7. /5x=50 /-7x=42 /3x- 24=0

0‚5-x=0‚1​

Answer 1

Resposta:

$2 + x = 7 \\ x = 9$

$5x = 50 \\ \\ x = \frac{50}{5} \\ \\ x = 10$

$- 7x = 42 \\ x = \frac{42}{ - 7} \\ \\ x = - 6$

$3x - 24 = 0 \\ 3x = 24 \\ \\ x = \frac{24}{ 3} \\ x = 8$

$0.5 - x = 0.1 \\ - x = 0.1 - 0.5 \\ - x = - 0.4 \\ x = \frac{ - 0.4}{ - 1} \\ \\ x = 0.4$
