Answer 1

Respuesta:

Ufff!!!

Explicación paso a paso:

a) x + 4 = 7

x = 7 - 4

x = 3

b) y + 4 = 1

y = 1 - 4

y = -3

c) x - 3 = -7

x = -7 + 3

x = -4

d) 2 - F = -9

-F = -9 - 2

-F = -11

multiplicamos todo por -1

F = 11

e) 3v = -15

v = $\frac{-15}{3}$

v = -5

f) -2e = 24

e = $\frac{24}{-2}$

e = -12

g) -5m = -35

m = $\frac{-35}{-5}$

m = 7

h) F ÷ 5 = -90

F = -90 * 5

F = -450

i) t ÷ (-4) = 28

t = 28 * (-4)

t = -112

j) -27 = 9v

v = $\frac{-27}{9}$

v = -3

k) -3x + 1 = 10

-3x = 10-1

x = $\frac{9}{-3}$

x = -3

l) 16 - 3x = 5x + 24

-3x - 5x = 24 -16

-8x = 8

x = $\frac{8}{-8}$

x = -1

m) -6y - 1 = -y + 9

-6y + y = 9 +1

-5y = 10

y = $\frac{10}{-5}$

y = -2

n) 2 · m + 40 = 60

2m = 60 - 40

m = $\frac{20}{2}$

m = 10

o) F + 5 · 3 = 60

F + 15 = 60

F = 60 - 15

F = 45

p) 25F - 10 = 65

25F = 65+10

F = $\frac{75}{25}$

F = 3

q) F · 3 +70 = 76

3F + 70 = 76

3F = 76 - 70

F = $\frac{6}{3}$

F = 2

r) v ÷ 3 + 8 - 2 = 10

$\frac{v}{3}$ + 8 - 2 = 10

$\frac{v}{3}$ + 6 = 10

multiplico por 3 para eliminar denominador

v + 18 = 30

v = 30-18

v = 12

s) t + 5 = 3t - (-3)

t - 3t = 3 - 5

-2t = -2

t = $\frac{-2}{-2}$

t = 1

t) e + 4e - 1 = e + 15

e + 4e - e = 15 + 1

4e = 16

e = $\frac{16}{4}$

e = 4

u) 8t - 3t = 35

5t = 35

t = $\frac{35}{5}$

t = 7

v) 2F = -28 ÷ (-2)

2F = $\frac{-28}{-2}$

2F = 14

F = $\frac{14}{2}$

F = 7

w) 36 ÷ (-4) = 3F

-9 = 3F

F = $\frac{-9}{3}$

F = -3
