Answer 1

Respuesta:

a) x = 3

b) x = 12

c) x = 11

d) x = 7

e) x = -4

f) x = 2

g) x = 6

h) x = -2

i) x = -5

j) x = 2

k) x = 1

l) x = -1

m) x = 14

n) x = 9

ñ) x = 2

Explicación paso a paso:

a) 6x-10=8 => x = 3

b) 2x+8=32 => x = 12

c) 2x+5=27 => x = 11

d) 2x-34=-20 => x = 7

e) 5x+4=-16 => x = -4

f) 4x-9=-1 => x = 2

g) 3x-6=12 => x = 6

h) 12x+8=-16 => x = -2

i) 8x+27=2x-3 => 6x = -30 => x = -5

j) 4x+3=3x+5 => x = 2

k) 6x+6=4+8x => -2x = -2 => x = 1

l) 9x+8=7x+6 => 2x = -2 => x = -1

m) 7x-12=5x+16 => 2x = 28 => x = 14

n) 3x-10=2x-1 => x = 9

ñ) 9+9x=17+5x => 4x = 8 => x = 2

Comprobación:

a) 6(3) - 10 = 8 => 18 - 10 = 8 => 8 = 8

b) 2(12) + 8 = 32 => 24 + 8 = 32 => 32 = 32

c) 2(11) + 5 = 27 => 22 + 5 = 27 => 27 = 27

d) 2(7) - 34 = -20 => 14 - 34 = -20 => -20 = -20

e) 5(-4) + 4 = -16 => -20 + 4 = -16 => -16 = -16

f) 4(2) - 9 = -1 => 8 - 9 = -1 => -1 = -1

g) 3(6) - 6 = 12 => 18 - 6 = 12 => 12 = 12

h) 12(-2) + 8 = -16 => -24 + 8 = -16 => -16 = -16

i) 8(-5) + 27 = 2(-5) - 3 => -40+27 = -10-3 => -13 = -13

j) 4(2) + 3 = 3(2) + 5 => 8 + 3 = 6 + 5 => 11 = 11

k) 6(1) + 6 = 4 + 8(1) => 6 + 6 = 4 + 8 => 12 = 12

l) 9(-1) + 8 = 7(-1) + 6 => -9+8 = -7+6 = -1 = -1

m) 7(14) - 12 = 5(14) + 16 => 98-12 = 70+16 => 86 = 86

n) 3(9) - 10 = 2(9) - 1 => 27-10 = 18-1 => 17 = 17

ñ) 9 + 9(2) = 17 + 5(2) => 9+18 = 17+10 => 27 = 27
