Answer:
3 & 4
Step-by-step explanation:
Given
[tex]\frac{2}{3}x = 10[/tex]
Required
Determine the number of ways to solve for x
From the list of given options, (1), (2) & (5) are incorrect, as they won't give the solution to the value of x
Option (3) is correct: See below
[tex]\frac{2}{3}x/\frac{2}{3} = 10/\frac{2}{3}[/tex]
[tex]\frac{2}{3}x*\frac{3}{2} = 10 * \frac{3}{2}[/tex]
[tex]x = 10 * \frac{3}{2}[/tex]
[tex]x = \frac{30}{2}[/tex]
[tex]x = 15[/tex]
Option (4) is also correct: See below
[tex]\frac{2}{3}x*\frac{3}{2} = 10 * \frac{3}{2}[/tex]
[tex]x = 10 * \frac{3}{2}[/tex]
[tex]x = \frac{30}{2}[/tex]
[tex]x = 15[/tex]
