Question

Me ayudan es ahora porfa

Answer 1

Explicación paso a paso:

b)

$7x - 11 = 10 \\ 7x = 10 + 11 \\ 7x = 21 \\ x = \frac{21}{7} \\ x = 3$

c)

$3b + 4 = 19 \\ 3b = 19 - 4 \\ 3b = 15 \\ b = \frac{15}{3} \\ b = 5$

d)

$9y - 15 = 21 \\ 9y = 21 + 15 \\ 9y = 36 \\ y = \frac{36}{9} \\ y = 4$

e)

$2d + 14 = 30 \\ 2d = 30 - 14 \\ 2d = 16 \\ d = \frac{16}{2} \\ d = 8$

espero haberte ayudado .

Answer 2

Explicación paso a paso:

7x-11=10

7x=10+11

7x=21

x=21/7

x=3

3b +4=19

3b=19-4=15

3b=15

b=15/3

b=5

9y-15=21

9y=21+15=36

9y=36

y= 36/9

y=4

2d+14=30

2d=30-14= 16

2d=16

d=16/2=8

d=8
