Question

Resolvam isso pra mim pfvrr???

Answer 1

Resposta:

a) x = 38

b) x = 25

c) x = 20

d) x = -39

e) x = -3

f) x = -44

g) x = -23

h) x = -44

Explicação passo-a-passo:

a) x = -12 + 50

x = 38

b) x = 45 - 20

x = 25

c) 3x -2x = 90 + 10

5x = 100

x = 100/5

x = 20

d)

4x -2x = -50 -28

2x = -78

x = -78/2

x = -39

e)

2x = 12 + 7 - 25

2x = -6

x = -6/2

x = -3

f)

10x - 5x = -125 - 95

5x = 220

x = 220/5

x = -44

g)

8x - 3x -3x = 38 - 14 - 70

2x = -46

x = -46/2

x = -23

h)

2x = -208 + 120

2x = -88

x = -88/2

x = -44
