____ has the same solution as _______ .
2(5x+4)=8x+28

x/2+4=5x-10

6x - 10 =50

5x/9=3

1 answer

To determine which two equations have the same solution, we will solve each equation step by step:

  1. Equation: \(2(5x+4)=8x+28\)

    Simplifying: \[ 10x + 8 = 8x + 28 \] Subtract \(8x\) from both sides: \[ 2x + 8 = 28 \] Subtract \(8\) from both sides: \[ 2x = 20 \] Divide by \(2\): \[ x = 10 \]

  2. Equation: \(\frac{x}{2}+4=5x-10\)

    Simplifying: \[ \frac{x}{2} + 4 = 5x - 10 \] Multiply through by \(2\) to eliminate the fraction: \[ x + 8 = 10x - 20 \] Subtract \(x\) from both sides: \[ 8 = 9x - 20 \] Add \(20\) to both sides: \[ 28 = 9x \] Divide by \(9\): \[ x = \frac{28}{9} \]

  3. Equation: \(6x - 10 = 50\)

    Simplifying: \[ 6x = 60 \] Divide by \(6\): \[ x = 10 \]

  4. Equation: \(\frac{5x}{9}=3\)

    Simplifying: \[ 5x = 27 \] Divide by \(5\): \[ x = \frac{27}{5} \]

Summary of Solutions:

  • First Equation: \(x = 10\)
  • Second Equation: \(x = \frac{28}{9}\)
  • Third Equation: \(x = 10\)
  • Fourth Equation: \(x = \frac{27}{5}\)

Conclusion:

The equations that have the same solution are:

2(5x+4)=8x+28 has the same solution as 6x - 10 = 50.

So the final answer is:

2(5x+4)=8x+28 has the same solution as 6x - 10 = 50.
