Solve the Linear Equation: Determine X from 1.5 - X = 2.8

To solve the equation $1.5 - x = 2.8$, follow these steps:

• Step 1: Add $x$ to both sides of the equation to get $1.5 = x + 2.8$.
• Step 2: Subtract $2.8$ from both sides to isolate $x$: $1.5 - 2.8 = x$.

Perform the subtraction: $1.5 - 2.8$ results in $-1.3$.

Thus, $x = -1.3$.

The solution to the problem is $\mathbf{x = -1.3}$.
