Justify your steps using properties of equality and determine the number of solutions to the equation 3/2(4-8×)+5×=1-7×

1 answer

To solve the equation \( \frac{3}{2}(4 - 8x) + 5x = 1 - 7x \) and justify the steps using properties of equality, let's follow through with the solution.

  1. Distribute \( \frac{3}{2} \) on the left side: \[ \frac{3}{2} \cdot 4 - \frac{3}{2} \cdot 8x + 5x = 1 - 7x \] \[ 6 - 12x + 5x = 1 - 7x \] (Distributive property)

  2. Combine like terms on the left side: \[ 6 - 7x = 1 - 7x \] (Combining like terms)

  3. Add \( 7x \) to both sides: \[ 6 = 1 \] (Addition property of equality)

At this point, \( 6 = 1 \) is a contradiction and indicates that there is no solution to the equation.

  1. Conclusion: Since we arrived at a contradiction, this means that there are no values of \( x \) that satisfy the equation.

Thus, the number of solutions to the equation \( \frac{3}{2}(4 - 8x) + 5x = 1 - 7x \) is 0 solutions.
