Question

Which equations have the same value of x as Three-fifths (30 x minus 15) = 72? Select three options.

Answer 1

The equivalent equations to $\frac{3}{5}(30x - 15) = 72$ 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 $\frac{3}{5}(30x - 15) = 72$, hence:

$\frac{3}{5}(30x - 15) = 72$

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.
