-3,6x+0,8=-6,4

To solve the equation \(-3.6x + 0.8 = -6.4\), follow these steps:

1. Isolate the term with \(x\): Subtract \(0.8\) from both sides of the equation: \[ -3.6x + 0.8 - 0.8 = -6.4 - 0.8 \] This simplifies to: \[ -3.6x = -7.2 \]

2. Solve for \(x\): Divide both sides by \(-3.6\): \[ x = \frac{-7.2}{-3.6} \] This results in: \[ x = 2 \]

Thus, the solution to the equation is \(x = 2\).
