Пошаговое объяснение:

[tex]-\dfrac{7}{8}x-\dfrac{5}{8}=\dfrac{25}{32}x-\dfrac{11}{28};[/tex]

[tex]-\dfrac{7}{4 \cdot 2}x-\dfrac{5}{4 \cdot 2}=\dfrac{25}{4 \cdot 8}x-\dfrac{11}{4 \cdot 7} \quad \bigg | \cdot (4 \cdot 8 \cdot 7)[/tex]

[tex]-7x \cdot 4 \cdot 7-5 \cdot 4 \cdot 7=25x \cdot 7-11 \cdot 8;[/tex]

[tex]-28x \cdot 7-140=25x \cdot 7-88;[/tex]

[tex]-28x \cdot 7-25x \cdot 7=140-88;[/tex]

[tex]-7x(28+25)=52;[/tex]

[tex]-7x \cdot 53=52;[/tex]

[tex]-7x=\dfrac{52}{53};[/tex]

[tex]x=-\dfrac{52}{53 \cdot 7};[/tex]

[tex]x=-\dfrac{52}{371};[/tex]

Verified answer

Ответ:

х = -52/371

Пошаговое объяснение:

-7/8x - 5/8 = 25/32x - 11/28

-7/8х - 25/32х = 5/8 - 11/28

-28/32х - 25/32х = 35/56 - 22/56

-53/32х = 13/56

х = 13/56: (-53/32)

х = 13/56 * (-32/53)

х = -52/371
