Question

ПОМОГИТЕ СРОЧНО!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer 1

3. 6y - (3 + y) = 3(y - 2)

Раскрываем скобки.

6y - 3 - y = 3y - 6

5y - 3y = -6 + 3

2y = -3

y = -1.5

5.  3y - 0,6 = 3,5y + 2

0.5y = -2,6

y = -5,2

p.s. прошу прощения, что так долго. Отвлекли)

p.p.s. в пятом ошибся со знаком, уже исправил.

Answer 2

Ответ:

$1.\;\;5.6x = 11-x\\\\6.6x = 11\\\\x = 1\frac{2}{3} \\\\\\2.\;\;7x-3 = 2x+4\\\\5x = 7\\\\x = 1.4\\\\\\3.\;\;6y-(3+y) = 3(y-2)\\\\6y-3-y = 3y-6\\\\2y = -3\\\\y = -1.5\\\\\\4.\;\;4\frac{2}{3} x = -\frac{7}{12}\;\;| *12\\\\56x = -7\\\\x = -8\\\\\\5. \;\;3y-0.6 = 3.5y+4\\\\-0.5y = 4.6\\\\y = -9.2\\\\\\6.\;\;\frac{2x-4}{5} = \frac{3x}{2}\;\;|*10\\ \\4x-8 = 15x\\\\-11x = 8\\\\x = -\frac{8}{11}$

$7.\;\;\frac{6x}{7}+\frac{x-5}{2} = 4\;\;|*14\\\\12x+7x-35 = 56\\\\19x = 91\\\\x = 4\frac{15}{19} \\\\\\8.\;\;\frac{6x-8}{2x+7} =\frac{16}{15}\\\\15(6x-8) = 16(2x+7)\\\\90x-120 = 32x+112\\\\58x = 232\\\\x = 4$
