Question

6(2x--3)-7(x+1,5)=3,5

Answer 1

12х-18-7х-10,5=3,5
5х=3,5+18+10,5
5х=32
х=32/5
х=6,4

Answer 2

To solve the equation 6(2x - 3) - 7(x + 1.5) = 3.5, we will follow the order of operations and simplify the equation step by step.

Let's begin:

1. Distribute the multiplication: 12x - 18 - 7x - 10.5 = 3.5

2. Combine like terms: (12x - 7x) + (-18 - 10.5) = 3.5 5x - 28.5 = 3.5

3. Move the constant term to the other side by adding 28.5 to both sides: 5x - 28.5 + 28.5 = 3.5 + 28.5 5x = 32

4. Divide both sides by 5 to solve for x: (5x)/5 = 32/5 x = 6.4

So, the solution to the equation 6(2x - 3) - 7(x + 1.5) = 3.5 is x = 6.4.
