Question

3x+18=90 -5m-7=700 .75y=27 3(x+6)=x+35

Answer 1

EXPLICACIÓN:

a)

3x + 18 = 90

3x = 90 - 18

3x = 72

x = 24

b)

-5m - 7 = 700

-5m = 700 + 7

-5m = 707

m = 707/-5

m = -14.14

c)

75y = 27

y = 27/75

y = 0.36

d)

3(x + 6) = x + 35

3x + 18 = x + 35

3x - x = 35 - 18

2x = 17

x = 8.5

Espero te sirva y suerteee!!! :)
