Question

URGENTE Sendo “x” a incógnita, resolva as seguintes equações literais no conjunto R.
a) 5x – 3a= 12a *
b) 6x + p = 4x + 2p *
c) 3(ax + b) = 2(ax –b) *
d) a + x/2 + a = 4 a – x/3 *​

Answer 1

Resposta:

a) 5x=12a+3a

5x= 15a

x=15a/5

x= 3a

b)6x-4x=2p-p

2x=p

x=p/2

c) 3ax+ 3b=2ax-2b

3ax-2ax= -2b-3b

ax=-5b

x= -5b/a

d) 2a+ x/2= 4a- x/3

x/2+ x/3= 4a-2a

mmc

3x+ 2x= 24a-12a

5x= 12a

x= 12a/5
