b) x = 199

c) x = 516

d) x = -2

e) x = -10

f) x = 4

g) x = 2

h) x = -3

i) x = 2

j) x = 6

k) x = 7

l) x = 12

m) x = 4

n) x = 3

o) x = 25/2

p) x = 29/2

q) x = -3/5

r) x = 5

s) x = 24

Explicação passo-a-passo:

a) x = 10 - 4 = 6

b) x = 300 - 101 = 199

c) x = 237 + 279 = 516

d) x = -10 + 8 = -2

e) x = -1 - 9 = -10

f) x = 12/3 = 4

g) x = 18/9 = 2

h) x = -105/35 = -3

i) 7x = 13 + 1 -> 7x = 14 -> x = 2

j) 6x - 2x = 14 + 10 -> 4x = 24 -> x = 6

k) 6x - 2x = 28 -> 4x = 28 -> x = 7

l) 2x - x = 18 - 6 -> x = 12

m) 5x - 2x = 9 + 3 -> 3x = 12 -> x = 4

n) 3x + 6 = 15 -> 3x = 9 -> x = 3

o) 2x - 2 = 16 + 7 -> 2x = 23 + 2 -> x = 25/2

p) 7x - 14 = 5x + 15 -> 7x - 5x = 15 + 14 -> 2x = 29 -> x = 29/2

q) 2x - 12 = -15 - 3x -> 2x + 3x = -15 + 12 -> 5x = -3 -> x = -3/5

r) 6x - 9 + 2x + 2 = 3x + 18 -> 6x + 2x - 3x = 18 + 9 - 2 -> 5x = 25 -> x = 5

s) 2x + 3x - 15 = 4x + 9 -> 2x + 3x - 4x = 9 + 15 -> x = 24
