z−6.4z−1.9=−4.9(z+6)

Sure, let's solve the equation step by step:

1. Distribute -4.9 to both terms in the parentheses on the right side of the equation:

   z - 6.4z - 1.9 = -4.9z - 29.4

2. Combine like terms on both sides of the equation:

   -5.4z - 1.9 = -4.9z - 29.4

3. Add 4.9z to both sides of the equation to get the z terms on one side:

   -0.5z - 1.9 = -29.4

4. Add 1.9 to both sides of the equation to isolate the z term:

   -0.5z = -27.5

5. Divide both sides of the equation by -0.5 to solve for z:

   z = 55

So, the solution to the equation is z = 55.
