Answer 1

Respuesta:

a) -2

b) 36

c) -16

d) 2

e) 2

f) 33

Explicación paso a paso:

a) 2x - 4 = - 8

2x = -8 + 4

x = -4/2

x = -2

b) $\frac{x + 4}{8} = 5$

x + 4 = 5(8)

x = 40 - 4

x = 36

c) 3a + 7 = 2a - 9

3a - 2a = -9 - 7

a = -16

d) 2 - 5p = -8

-5p = -10

p = -10/-5

p = 2

e) -m + 3 = -9m + 19

-m + 9m = 19 - 3

8m = 16

m = 16/8

m = 2

f) $-7 = \frac{12 - h}{3}$

(-7)3 = 12 - h

-21 - 12 = -h

-33 = -h

h = 33
