0,8*(6х-7)=0,5*(3х+7)

0,8*6х-0,8*7=0,5*3х+0,5*7

4,8х-5,6=1,5х+3,5

4,8х-1,5х=3,5+5,6

3,3х=9,1

х=9,1/3,3

х=2,7575 и т.д. или 2 25/33

Answer 3

To solve the equation 0.8 * (6x - 7) = 0.5 * (3x + 7), we can follow these steps:

1. Distribute the multiplication on both sides of the equation: 0.8 * 6x - 0.8 * 7 = 0.5 * 3x + 0.5 * 7

   Simplifying this equation gives: 4.8x - 5.6 = 1.5x + 3.5

2. Move all the terms containing x to one side of the equation by subtracting 1.5x from both sides: 4.8x - 1.5x - 5.6 = 1.5x - 1.5x + 3.5

   Simplifying this equation gives: 3.3x - 5.6 = 3.5

3. Add 5.6 to both sides of the equation: 3.3x - 5.6 + 5.6 = 3.5 + 5.6

   Simplifying this equation gives: 3.3x = 9.1

4. Divide both sides of the equation by 3.3 to solve for x: (3.3x) / 3.3 = 9.1 / 3.3

   Simplifying this equation gives: x = 2.7575757576 (approximately)

Therefore, the solution to the equation 0.8 * (6x - 7) = 0.5 * (3x + 7) is x ≈ 2.7575757576.
