Question

Resolver as equações em R:
a) 3( x – 1 ) + 2 ( x – 3 ) = 6 b) 5 ( x – 2 ) – 3 ( x + 1 ) = 7 c) 2 ( 2x – 4 ) – 3 ( x – 2 ) = x + 9
d) - = e) - = f) - = 1

Answer 1

Resposta:

a)3x-3+2x-6=6

5x-9=6

5x=6+9

5x=15

x=15/5

x=3

b)5x-10-3x-3=7

2x-13=7

2x=7+13

2x=20

x=20/2

x=10

c)4x-8-3x+6=x+9

x-2=x+9

d)
