Answer 1

Ответ:

$4x = 24 + x \\ 4x - x = 24 \\ 3x = 24 \\ x = 24 \div 3 \\ x = 8$

$8x - 8 = 20 - 6x \\ 8x + 6x = 20 + 8 \\ 14x = 28 \\ x = 28 \div 14 \\ x = 2$

$9 - 4x = 3x - 40 \\ - 4x - 3x = - 40 - 9 \\ - 7x = - 49 \\ x = - 49 \div - 7 \\x = 7$

$0.6x - 5.4 = - 0.8x + 5.8 \\ 0.6x + 0.8x = 5.8 + 5.4 \\ 1.4x = 11.2 \\ x = 11.2 \div 1.4 \\ x = 8$
