Question

4,7*(-4у-3)-3,5*(6-2у)=0,3

Answer 1

4.7(-4у-3)-3.5(6-2у)=0.3
-18.8у-14.1-21+7у=0.3
-11.8у-35.1=0.3
-11.8у=0.3+35.1
-11.8у=35.4
у=35.4\(-11.8)
у=-3

Answer 2

To solve the equation 4.7*(-4u-3)-3.5*(6-2u)=0.3, we can follow these steps:

Step 1: Distribute the multiplication Multiply each term inside the parentheses by the coefficient outside the parentheses:

4.7 * (-4u) + 4.7 * (-3) - 3.5 * 6 + 3.5 * (-2u) = 0.3

Step 2: Simplify the expressions Multiply the values:

-18.8u - 14.1 - 21 + (-7u) = 0.3

Simplify the expression:

-18.8u - 7u - 14.1 - 21 = 0.3

Step 3: Combine like terms Combine the terms with the same variable:

-25.8u - 35.1 = 0.3

Step 4: Move constants to the other side Move the constant term to the right side of the equation by adding 35.1 to both sides:

-25.8u = 0.3 + 35.1

Simplify:

-25.8u = 35.4

Step 5: Solve for u Divide both sides of the equation by -25.8 to solve for u:

u = 35.4 / -25.8

Simplify:

u ≈ -1.37

Therefore, the solution to the equation 4.7*(-4u-3)-3.5*(6-2u)=0.3 is u ≈ -1.37.
