Sagot :

The equivalent equations to [tex]\frac{3}{5}(30x - 15) = 72[/tex] are given as follows:

  • 18 x - 9 = 72
  • 3(6x - 3) = 72
  • x = 4.5.

What are equivalent equations?

Equivalent equations are equations that have the same solution.

First, we have to check the solution to [tex]\frac{3}{5}(30x - 15) = 72[/tex], hence:

[tex]\frac{3}{5}(30x - 15) = 72[/tex]

Applying the fraction:

18x - 9 = 72 -> first equivalent equation

Simplifying by 3:

3(6x - 3) = 72 -> second equivalent equation

The solution is:

18x - 9 = 72

18x = 81

x = 81/18

x = 4.5 -> third equivalent equation.
