Answer 1

-9(-5+7х)-7х=-25

45-63х-7х=-25

-70х+45=-25

-70х=-25-45

-70х=-70

х=1

ОТВЕТ: Х=1

Answer 2

Ответ:

Х = 1

Пошаговое объяснение:

-9(-5+7х)-7х=-25

45 - 63Х - 7Х = -25

45 + 25 = 63Х + 7Х

70Х = 70

Х = 70 : 70

Х = 1

Answer 3

To solve the equation, let's simplify and solve step by step:

-9(-5+7x) - 7x = -25

Start by simplifying the expression within parentheses:

-9(-5) + (-9)(7x) - 7x = -25

Multiply the terms:

45 - 63x - 7x = -25

Combine like terms:

-63x - 7x = -25 - 45

-70x = -70

Divide both sides by -70 to isolate x:

x = (-70) / (-70)

Simplify:

x = 1

Therefore, the solution to the equation is x = 1.
