Question

2(х-1)-7=5х-5 .... Хелп...

Answer 1

2x-2-7=5x-5

2x-9=5x-5

2x-5x=-5+9

-3x=4

x=-4/3

Answer 2

To solve the equation 2(x - 1) - 7 = 5x - 5, we'll follow these steps:

Step 1: Distribute the 2 to the terms inside the parentheses: 2x - 2 - 7 = 5x - 5

Step 2: Combine like terms: 2x - 9 = 5x - 5

Step 3: Move the x terms to one side and the constant terms to the other side. To do this, we'll subtract 2x from both sides and add 5 to both sides: 2x - 2x - 9 + 5 = 5x - 2x - 5 + 5

Simplifying: -9 + 5 = 3x - 5

Step 4: Combine like terms: -4 = 3x - 5

Step 5: Add 5 to both sides: -4 + 5 = 3x - 5 + 5

Simplifying: 1 = 3x

Step 6: Divide both sides by 3: 1/3 = 3x/3

Simplifying: 1/3 = x

So the solution to the equation is x = 1/3.
