Question

2,5х-2=3(х+1) пжжжжжжж​

Answer 1

2,5х-2 = 3(х+1)

2,5х-2 = 3х+3

2,5х-3х = 3+2

-0,5х = 5

х = -10

Answer 2

To solve the equation 2.5x - 2 = 3(x + 1), we'll simplify and solve for x step by step:

1. Distribute 3 on the right side: 2.5x - 2 = 3x + 3

2. Subtract 2.5x from both sides to isolate the x term on the left side: 2.5x - 2.5x - 2 = 3x - 2.5x + 3 -2 = 0.5x + 3

3. Subtract 3 from both sides: -2 - 3 = 0.5x + 3 - 3 -5 = 0.5x

4. Divide both sides by 0.5 to solve for x: -5/0.5 = (0.5x)/0.5 -10 = x

Therefore, the solution to the equation 2.5x - 2 = 3(x + 1) is x = -10.
