Question

Me ajudem , é bem facil, preciso dos calculos pfv

Answer 1

a) x + 5 = 8 -> x = 8 - 5 -> x = 3

b) x - 4 = 3 -> x = 3 + 4 -> x = 7

c) x + 6 = 5 -> x = 5 - 6 -> x = -1

d) x - 7 = - 7 -> x = -7 + 7 -> x = 0

e) x + 9 = -1 -> x = -1 - 9 -> x = -10

f) x - 39 = - 79 -> x = -79 + 39 -> x = -40

g) 10 =x + 8 -> x = 8 - 10 -> x = -2

h)15 = x + 20 -> x = 20 - 15 = x = 5

i) 4 = x -10 -> x = -10 - 4 -> x= -14

j) 7 = x + 8 -> x = 8 -7 -> x = 1

k) x - 1 = 5 -> x = 5 + 1 -> x = 6

l) 2x + 4 = 16 -> 2x = 16 - 4 -> 2x = 12 -> x = 12/2 -> x = 6

m) 3x = 15 -> x = 15/3 -> x = 5

n) 2x = 10 -> x=10/2 -> x = 5

o) 3x = -9 -> x = -9/3 -> x = -3

p) 2x - 2 = 12 - 5x -> 2x + 5x = 12 + 2 -> 7x = 14 -> x = 14/7 -> x = 2

q) 3x - 13 = 8 -> 3x = 8 + 13 -> 3x = 21 -> x = 21/3 -> x = 7

r) 4x - 9 = 23 -> 4x = 23 + 9 -> 4x = 32  -> x = 32/4 -> x = 8

s) 7x - 33 = -12 -> 7x = -12 + 33 -> 7x = -21 -> x = -1/7 -> x = -3

t) 33 + x = 5 - 3x -> x + 3x = 5 - 33 -> 4x = -28 -> x = -28/4 -> x = -7

u) 2x = 14 -> x = 14/2 -> x = 7

v) 7x = -21 -> x = -21/7 -> x = -3

w) 4x = -12 -> x = -12/4 -> x = -3

x)35x = -105 -> x = -105/35 -> x = -3
