Ответ:

x+4,5+2x+6,5=3x+4,5+6,5=3x+11

Answer 2

Solving the Expression x + 4.5 = 2x + 6.5

To solve the given expression x + 4.5 = 2x + 6.5 using the laws of addition, we can follow these steps:

1. Isolate the variable x on one side of the equation: Subtract x from both sides of the equation to isolate x on one side.

2. Simplify and solve for x: Once x is isolated, simplify the equation and solve for x.

Let's proceed with the solution:

1. Isolate the variable x: Subtract x from both sides of the equation: x + 4.5 - x = 2x + 6.5 - x 4.5 = x + 6.5

2. Simplify and solve for x: Subtract 6.5 from both sides of the equation: 4.5 - 6.5 = x -2 = x

So, the value of x that makes the given expression true is x = -2.

This solution is based on the laws of addition and the principles of solving linear equations.
