AYUDAAAAAA ES PARA MAÑANA
a. -p + (3 + 2 p) • (-2) = 24
c. 3+3r-4. (1-1)=1-31
e. (S-1).(-4) - 7 = 25
g. 5 n– 8 n+3 = -3(7 – n)
b.-16 = 3x-2.(3-X)
d.-3 m -2.(3-m) = -m - 6
f. -7 x + 8 = 4 x - 14
h.-2 m +3.(3-m) = m - 9​

Answer 1

a)-p+(3+2p)*(-2)=24

-p-6-4p=24

-5p=30

p=-6

comprobamos:

--6+(3+2*-6)*(-2)=24

6+(3-12)(-2)=24

6+(-9)(-2)=24

6+18=24

24=24

por lo tanto p=-6

c)3+3r-4*(1-1)=1-31

3+3r-4*0=-30

3r=-33

r=-11

e)(S-1)*(-4) - 7 = 25

-4s+4-7=25

-4s=28

s=-7

g)5 n– 8 n+3 = -3(7 – n)

-3n+3=-21+3n

-6n=-24

n=4

b)-16 = 3x-2*(3-X)

-16=3x-6+2x

-16=5x-6

-10=5x

x=-2

d)-3 m -2*(3-m) = -m - 6

-3m-6+2m=-m-6

-m-6=-m-6

m=infinito

f)-7 x + 8 = 4 x - 14

-11x=-22

x=2

h)-2 m +3*(3-m) = m - 9

-2m+9-3m=m-9

-5m=m-18

-6m=-18

m=3
