AJUDAAAA!!!!!!!!!

É NECESSÁRIO TER A RESULUÇÃO!

1- Calcule o valor de x das seguintes equações:

a) 8.x - 3.x = 10 + 5

b) 7.x - 5.x = 8 - 4

c) 4.x = 16

d) 6.x = 37 - 1

e) 10.x = 50

f) 2.x = 12 + 16

g) 4.x = 28

h) 4.x - 2.x = 5 - 3

i) 4.x - 14 = 2.x + 8

j) 3.x - 2.x = 45 + 4

k) 6.x + 4.x - 3.x = 168

l) 2.x + 3.x + 8 = 48

m) 10.x = 150

n) x - 2 = 33

o) 2.x + x = 90

p) 4.x + 4.x = 100 + 4

q) x = 28 - 1

r) 10.x - 8.x - x = 20 + 8

s) 2.x + x = 99

t) x = 3 . 15

Answer 1

1)

A- 8X - 3X = 10 + 5

5X = 15

X = 15/5

X = 3

B) 7X - 5X = 8 - 4

2X = 4

X = 4/2

X = 2

C) 4X = 16

X = 16/4

X= 4

D) 6X = 37 - 1

6x = 36

X = 36/6

X = 6

E) 10x = 50

X = 50/10

X= 5

F) 2x = 12 + 16

2x = 28

X = 28/2

X = 14

G) 4x = 28

X = 28/4

X=7

H) 4x - 2x = 5 - 3

2x = 2

X = 2/2

X = 1

I) 4x - 14 = 2x + 8

4x + 2x = 14 - 8

6x = 6

X = 6/6

X= 1

J) 3x - 2x = 45 + 4

X = 49

K) 6x + 4x - 3x = 168

10x - 3x = 168

7x = 168

X = 168/7

X = 24

L) 2x + 3x + 8 = 48

2x + 3x = 48 - 8

5x = 40

X = 40/5

X= 8

M) 10x = 150

X = 150/ 10

X= 15

N) x - 2 = 33

X= 33 + 2

X=35

O) 2x + x = 90

3x = 90

X = 90 /3

X = 30

P) 4x + 4x = 100 + 4

8x = 104

X = 104/8

X = 27

Q) x = 28 - 1

X = 27

R) 10x - 8x - x = 20 + 8

2x - x = 28

X = 28

S) 2x - x = 99

3x = 99/3

X = 33

T) x = 3 × 15

X = 45

Espero ter ajudado!
