Question

1. Resolva as equações (tem que ter a conta junto):

h) x + 2 = - 10
i) 2x - 32 = -44
j) 2x - 6 = 40
k) 7x - 1 = 6
l) 5x - 9 = 11
m) x - 3 = 13
n) 6x - 25 = 11
o) 9x - 18 = 81
p) 8x - 14 = 7+ x

Answer 1

H) ×+2=-10 , ×=-10-2. , ×=-12
I)2×-32=-44 , 2×=-44+32 , 2×=-12 , ×=-12/2 , ×=-6
J)2×-6=40 , 2×=40+6 2×=46 , ×=46/2 , ×=23
K)7x-1=6 , 7×=6+1 , 7x=7 , ×=7/7 ×=1
L)5×-9=11 , 5×=11+9 , 5×=20 , ×=20/5 , ×=4
M)×-3=13 , ×=13+3 , ×=16
N)6×-25=11 , 6×=11+25 , 6×=36 , ×=36/6 ×=6
O)9×-18=81 , 9×=81+18 , 9×=99 , x=99/9 ×=11
P)8×-14=7+× , 8×-×=7+14 , 7×=21 , ×=21/7 ×=3

Espero ter ajudado !!!

Answer 2

H) x + 2 = -10
X= -10+2
X= -8
I) 2x -32= -44
2x= -44+32
2x= -12
X=-12/2
X=-6
J) 2x-6= 40
2x= 40+6
2x= 46
X= 23
K) 7x-1=6
7x=6+1
7x=7
X= 7/7
X=1
L) 5x-9=11
5x= 11+9
5x= 20
X= 20/5
X=4
M)x-3=13
X= 13+3
X=16
N)6x-25=11
6x= 11+25
6x= 36
X=36/6
X=6
O)9x-18=81
9x= 81+18
9x= 99
X= 99/9
X =11
P) 8x-14=7 + x
8x-x= 7+14
7x=21
X=21/7
X=3
