Question

6,4 * (у-12,8 )= 3,2

Answer 1

6.4х-81.92=3.2
6.4х=85.12
х=13.3

Answer 2

To solve the equation 6.4 * (у - 12.8) = 3.2, we can begin by simplifying the equation:

6.4 * у - 6.4 * 12.8 = 3.2

Next, we can distribute 6.4 to the terms inside the parentheses:

6.4у - 82.24 = 3.2

Now, let's isolate the variable у by moving the constant term to the other side of the equation:

6.4у = 3.2 + 82.24

Combine the constant terms:

6.4у = 85.44

Finally, solve for у by dividing both sides of the equation by 6.4:

у = 85.44 / 6.4

у ≈ 13.35
