2.25(x-4.2)=x+3.28

10.184

That's what I got. thanks

To solve the equation 2.25(x-4.2)=x+3.28, we need to isolate the variable x. Here's how to do it step by step:

1. Start by distributing the 2.25 to both terms inside the parentheses:
2.25 * x - 2.25 * 4.2 = x + 3.28

Simplify this equation:
2.25x - 9.45 = x + 3.28

2. Next, we want to get rid of the x term on the right side by subtracting x from both sides:
2.25x - 9.45 - x = x + 3.28 - x

Simplify this equation:
1.25x - 9.45 = 3.28

3. Now, we want to isolate the term with the variable, so we need to get rid of the constant term -9.45. We can do this by adding 9.45 to both sides:
1.25x - 9.45 + 9.45 = 3.28 + 9.45

Simplify this equation:
1.25x = 12.73

4. Finally, we can solve for x by dividing both sides by 1.25:
(1.25x) / 1.25 = 12.73 / 1.25

Simplify this equation:
x = 10.184

Therefore, the solution to the equation 2.25(x-4.2)=x+3.28 is x = 10.184.
