Question

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

Answer 1

Respostas:

a)3+x=0

x = 0 - 3

x = -3

b)23x+2=2

23x = 2 - 2

x = 0/23

x = 0

c)12-7+4x=25

4x = 25 - 12 + 7

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
