Explicación paso a paso:

$2x + 1 = 15 \\ 2x = 15- 1 \\ x = 14 \div 2 \\ x = 7$

$6x + 2 = 20 \\ 6x = 20 - 2 \\ x = 18 \div 6 \\ x = 3$

$7x - 10 = 53 \\ 7x = 53 + 10 \\ x = 63 + 7 \\ x = 9$

$9x + 4 = 22 \\ 9x = 22 - 4 \\ x = 18 \div 9 \\ x = 2$

$6 - 4x = 14 \\ - 4x = 14 - 6 \\ x = 8 \div ( - 4) \\ x = - 2$

$12 + 2x = 22 \\ 2x = 22 - 12 \\ x = 10 \div 2 \\ x = 5$

ESPERO SEA DE AYUDA
