Question

решите уравнение,спасибо заранее!

Answer 1

Ответ:

$\frac{7x-3}{6} = \frac{5x+1}{2} \\\\2(7x-3) = 6(5x+1)\\14x - 6 = 30x + 6\\30x - 14x = -6 - 6\\ 16x = -12\\x = -\frac{12}{16} \\\\x = - \frac{3}{4} = -0,75$

Answer 2

7x-3/6 - 5x+1/2 = 0

7x-3-(3*(5x+1))/6=0

7x-3-15x-3=0

-8x-6=0

-8x=6

x= - 0,75
