Question

resuelva cada situacion:

5a/3 + 4 = 78 - 9a/2

Answer 1

5$\frac{a}{3}$ + 4 = 78 - 9$\frac{a}{2}$
3(5$\frac{a}{3}$ + 4 = 78 - 9$\frac{a}{2}$)
5a + 12 =  234 - 27$\frac{a}{2}$
2(5a + 12 =  234 - 27$\frac{a}{2}$)
10a + 24 = 468 - 27a
10a + 27a = 468 - 24
37a = 444
a = 12

Comprobación

5$\frac{a}{3}$ + 4 = 78 - 9$\frac{a}{2}$
5$\frac{12}{3}$ + 4 = 78 - 9$\frac{12}{2}$
20 + 4 = 78 - 54
24 = 24
