Question

Me ajude a resolver as equações:
a) n-1 = 2 b) n-8 = 10 c) n+15 = 35 d) 6n = 30 e) n+n+n = 15 i) n+n+n = 36 j) n- 15 = 0

Answer 1

a) n-1=2
n=2+1
n=3
b) n-8=10
n=10+8
n=18
c) n+15=35
n=35-15
n=20
d) 6n=30
n=30/6
n=5
e) n+n+n=15
3n=15
n=15/3
n=5
i) n+n+n=36
3n=36
n=36/3
n=12
j) n-15=0
n=0+15
n=15

Answer 2

a)  n - 1 = 2
n = 2 + 1
n = 3

b) n - 8 = 10
n = 10 + 8
n = 18

c) n + 15 = 35
n = 35 - 15
n = 20

d) 6n = 30
n = 30/6
n = 5

e) n + n + n = 15
3n = 15
n = 15/3
 n = 5

i) n + n + n = 36
3n = 36
n = 36/3 
n = 12

j) n - 15 = 0
n = 15
