Question

(3-x)∙9=-36;x∙(-3,6)+2=6 4/5. СРОЧНО!!!!!!!

Answer 1

$1) \: (3 - x) \times 9 = - 36 \\ 27 - 9x = - 36 \\ - 9x = - 63 \\ x = 63 \div 9 \\ x = 7 \\ 2) \: x \times ( - 3.6) + 2 = 6 \frac{4}{5} \\ - 3.6x + 2 = 6.8 \: \\ - 1.8x + 1 = 3.4 \\ - 1.8x = 2.4 \\ - 18x = 24 \\ - 3x = 4 \\ x = - \frac{4}{3} \\ x = - 1 \frac{1}{3}$
