Using the properties of equality Find a solution to the equation 2f/5-8/5+2f=8

1 answer

To solve the equation \( \frac{2f}{5} - \frac{8}{5} + 2f = 8 \), we will use the properties of equality.

  1. Combine like terms: First, let's express \( 2f \) with a common denominator of 5: \[ 2f = \frac{10f}{5} \] So the equation can be rewritten as: \[ \frac{2f}{5} - \frac{8}{5} + \frac{10f}{5} = 8 \]

  2. Simplify the left side: Combine the fractions: \[ \frac{2f + 10f - 8}{5} = 8 \] This simplifies to: \[ \frac{12f - 8}{5} = 8 \]

  3. Eliminate the fraction: Multiply both sides by 5 to eliminate the fraction: \[ 12f - 8 = 40 \]

  4. Isolate \(12f\): Add 8 to both sides: \[ 12f = 40 + 8 \] This simplifies to: \[ 12f = 48 \]

  5. Solve for \(f\): Divide both sides by 12: \[ f = \frac{48}{12} \] Therefore, we get: \[ f = 4 \]

So, the solution to the equation is \( f = 4 \).
