To solve the equation \(-8x + 13 = -19\), follow these steps:

  1. Subtract 13 from both sides to isolate the term containing \(x\):

    \[ -8x + 13 - 13 = -19 - 13 \]

    This simplifies to:

    \[ -8x = -32 \]

  2. Next, divide both sides by -8 to solve for \(x\):

    \[ x = \frac{-32}{-8} \]

    This simplifies to:

    \[ x = 4 \]

Thus, the solution of the equation is \(x = 4\).

What is the solution of the equation 11−4x=−9 ?
−1/2
1/2

−5

To solve the equation \( 11 - 4x = -9 \), follow these steps:

  1. Start by isolating the term with \( x \). Subtract 11 from both sides:

    \[ 11 - 4x - 11 = -9 - 11 \]

    This simplifies to:

    \[ -4x = -20 \]

  2. Next, divide both sides by -4 to solve for \( x \):

    \[ x = \frac{-20}{-4} \]

    This simplifies to:

    \[ x = 5 \]

Thus, the solution of the equation is \( x = 5 \).

What is the solution of the equation 2/5x+4=1/5?
−2/19
−19/2
21/2
−38/25

To solve the equation \(\frac{2}{5}x + 4 = \frac{1}{5}\), follow these steps:

  1. Start by isolating the term with \(x\). Subtract 4 from both sides of the equation:

    \[ \frac{2}{5}x + 4 - 4 = \frac{1}{5} - 4 \]

    \[ \frac{2}{5}x = \frac{1}{5} - \frac{20}{5} \]

    \[ \frac{2}{5}x = \frac{1 - 20}{5} = \frac{-19}{5} \]

  2. Next, multiply both sides by the reciprocal of \(\frac{2}{5}\) to solve for \(x\):

    \[ x = \frac{-19}{5} \cdot \frac{5}{2} \]

    \[ x = \frac{-19 \cdot 1}{2} = \frac{-19}{2} \]

Thus, the solution of the equation is \(x = -\frac{19}{2}\).

What is the solution of the equation 53−2x=16?
3/4
3
−11/3
−11/12

To solve the equation \(53 - 2x = 16\), follow these steps:

  1. Start by isolating the term with \(x\). Subtract 53 from both sides of the equation:

    \[ 53 - 2x - 53 = 16 - 53 \]

    This simplifies to:

    \[ -2x = -37 \]

  2. Next, divide both sides by -2 to solve for \(x\):

    \[ x = \frac{-37}{-2} \]

    Simplifying gives:

    \[ x = \frac{37}{2} \]

The value \(\frac{37}{2}\) is not one of the options provided. Thus, we can recheck the calculation for any errors; however, there are no mistakes in the computation, and the solution is indeed \(x = \frac{37}{2}\) or \(18.5\).

It appears that none of the provided options (\(\frac{3}{4}, 3, -\frac{11}{3}, -\frac{11}{12}\)) are correct. Would you like to check for any other values or re-evaluate the question?
