Question

Помогите пожалуйста.

Answer 1

$7x - 5 = 6x + 1 \\ 7x - 6x = 1 + 5 \\ x = 6$

$4x - 3 = 2x + 5 \\ 4x - 2x = 5 + 3 \\ 2x = 8 \\ x = 8 \div 2 \\ x = 4$

$9 - 8y = - 6y + 1 \\ - 6y + 8y = 9 - 1 \\ 2y = 8 \\ y = 8 \div 2 \\ y = 4$

$6m + 3 = 7m + 8 \\ 7m - 6m = 3 - 8 \\ m = - 5$

$3(x + 2) = 18 \\ 3x + 6 = 18 \\ 3x = 18 - 6 \\ 3x = 12 \\ x = 12 \div 3 \\ x = 4$

$4(x - 3) - 12x = 3(2 - x) + 7 \\ 4x - 12 - 12x = 6 - 3x + 7 \\ - 3x + 8x = - 12 - 13 \\ 5x = - 25 \\ x = - 25 \div 5 \\ x = - 5$
