Final answer:

The algebraic equation 8.2(6x-3) - 7(7x-1.2) has one solution, which is x = 81. This is derived by expanding the equation, simplifying, and solving for x.

Step-by-step explanation:

The question is asking to determine the number of solutions to the algebraic equation 8.2(6x-3) - 7(7x-1.2).

To solve this, let's first expand the equation:


  • 8.2 * 6x - 8.2 * 3 = 49.2x - 24.6

  • - (7 * 7x - 7 * 1.2) = -49x + 8.4

Combine like terms:


  • 49.2x - 49x = 0.2x

  • -24.6 + 8.4 = -16.2

Now we have 0.2x - 16.2 = 0. Solving for x:


  • x = 16.2 / 0.2

  • x = 81

Since we found a single value for x, this equation has one solution. Always check to see if the solution is reasonable by substituting back into the original equation.
