Question

¿Podrían ayudarme con estas ecuaciones?
y/4 + 2 = 18

a/8 + 3=12

x/7 - 2 = 21

y/a - 2 = 10

a/5 - 4 = 13

a/4 - 3 = 52

Answer 1

Resolver.

y/4 + 2 = 18

y/4 = 18 - 2

y/4 = 16

y = 16(4)

y = 64

...........................................................

a/8  + 3 = 12

a/8 = 12 - 3

a/8 = 9

a = 9(8)

a = 72

.............................................................

x/7 - 2 = 21

x/7 = 21 + 2

x/7 = 23
 
x = 23(7)

x = 161.

.......................................................................

y/a - 2 = 10

y/a = 10 + 2

y/a = 12

y = 12(a)

y = 12a  ← no tiene solución.

................................................................

a/5 - 4 = 13

a/5 = 13 + 4

a/5 = 17

a = 17(5)

a = 85

.....................................................................

a/4 - 3 = 52

a/4 = 52 + 3

a/4 = 55

a = 55(4)

a = 220
