Question

1)Resolva as equações:

A) x-8=14
B)3x-6=
C)5-x=10
D)12x-22=122
E)-2x=6x+16

H)45x=90
I)35-7x=35
J)8x+40=-8
K)-x=20+x
L)11x+13=-9

Preciso disso para hoje!com as contas por favor;-)

Answer 1

a)x=14+8
x=22

b) incompleta


c)-x=10-5
-x=5 ×(-1)
x=-5

d)12x=122+22
12x=144
$x = \frac{144}{12}$
$x = 12$

e)-8x=16
$x = \frac{16}{ - 8}$
x=-2

f) incompleta

g)13x=-208+13
13x=195
$x = \frac{195}{13}$



h)
$x = \frac{90}{45}$
x=2

i)-7x=35-35
-7x=0
$x = \frac{0}{ - 7}$

x=0

j)8x=-48
$x = \frac{ - 48}{8}$
x=-6

k)-2x=20
$x = \frac{20}{ - 2}$
x= -10

l) 11x=-13-9
11x=-22
$x = \frac{ - 22}{11}$
x=-2
