Question

Resolva em R as equações a seguir:
a) 3+X=0
b)23X +2=2
c)12-7+4X =25
d)5X -3X=30
e)4X+10=45-3X

Me ajudem pfv

Answer 1

Resposta:

A) 3 + X = 0

X = – 3

B) 23x + 2 = 2

23x = 2 – 2

23x = 0

X = 0/23

X = 0

C) 12 – 7 + 4x = 25

4x = 25 – 12 + 7

4x = 13 + 7

4x = 20

X = 20/4

X = 5

D) 5x – 3x = 30

2x = 30

X = 30/2

X = 15

E) 4x + 10 = 45 – 3x

4x + 3x = 45 – 10

7x = 35

X = 35/7

X = 5

Abraço!
