Question

ayuda Porfa, no entiendo​

Answer 1

Respuesta:

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

$x - 18 = 24 \\ x = 24 + 18 \\ x = 42$

$2x + 4 = 32 \\ 2x = 32 - 4 \\ 2x = 28 \\ x = \frac{28}{2} \\ x = 14$

$5x - 5 = 15 \\ 5x = 15 + 5 \\ 5x = 20 \\ x = \frac{20}{5} \\ x = 4$

$6x + 6 = 36 \\ 6x = 36 - 6 \\ 6x = 30 \\ x = \frac{30}{6} \\ x = 5$
