Answer:
21
Step-by-step explanation:
[tex]10 + \frac{2x}{3} = 24[/tex]
to remove the denominator, multiply both sides with 3
[tex]3(10 + \frac{2x}{3} ) = (24)3[/tex]
[tex]30 + 2x = 72[/tex]
[tex]2x = 72 - 30[/tex]
[tex]2x = 42[/tex]
[tex]x = 21[/tex]
check:
two thirds of 21 is 14
[tex]10 + 14 = 24[/tex]
