Question

А) 7x – 4 = 3х – 9;

Answer 1

-Ответ:-1 1/4 (дробь)

Пошаговое объяснение:
7x-3x=-9+4
4x=-5
x = -5:4
X=-5/4(дробь)=-1 1/4(дробь)

Answer 2

7x-4=3x-9
7x-3x=-9+4
4x=-5
x=-1.25

Answer 3

To solve the equation 7x - 4 = 3x - 9, we'll start by isolating the variable x on one side of the equation. Here's the step-by-step solution:

1. Begin by subtracting 3x from both sides of the equation to eliminate the variable term on the right side: 7x - 3x - 4 = 3x - 3x - 9 4x - 4 = -9

2. Next, add 4 to both sides of the equation to isolate the constant term on the left side: 4x - 4 + 4 = -9 + 4 4x = -5

3. Finally, divide both sides of the equation by 4 to solve for x: (4x)/4 = (-5)/4 x = -5/4

So, the solution to the equation 7x - 4 = 3x - 9 is x = -5/4.
