Question

-3(4х-0,6y)-(-x+2,8y)

Answer 1

-3(4х-0,6y)-(-x+2,8y)=-12x+1.8y+x-2.8y=-11x-y

Answer 2

-3(4x-0,6y)-(-x+2,8y)= -12x+1,8y+x-2,8y=-11x-y

Answer 3

Let's simplify the given expression step by step:

-3(4x - 0.6y) - (-x + 2.8y)

Step 1: Distribute the -3 across the terms inside the first parentheses:

-3 * 4x + (-3) * (-0.6y) - (-x + 2.8y)

Step 2: Simplify the terms:

-12x + 1.8y - (-x + 2.8y)

Step 3: Distribute the negative sign in front of the second parentheses:

-12x + 1.8y + x - 2.8y

Step 4: Combine like terms:

(-12x + x) + (1.8y - 2.8y)

Step 5: Simplify further:

-11x - 1y

The final simplified expression is:

-11x - y
