tentukan penyelesaian dari persamaan : 3a+18/4=10a-2/3

[tex]3a + \frac{18}{4} = 10a - \frac{2}{3} [/tex]
[tex] \frac{54}{12} + \frac{8}{12} = 10a - 3a[/tex]
[tex] \frac{62}{12} = 7a[/tex]
[tex]a = \frac{62}{12} \div 7[/tex]
[tex]a = 0.738[/tex]

3a+18/4 =10a -2/3
18/4 + 2/3 = 10a-3a
9/2 +2/3 = 7a
31/6 = 7a
a= 31/56
