Answer 1

Respuesta:

A) 5x+5=20

5x=20-5

5x=15

x=15/5

x=3

B) 9z-9=108

9z=108+9

9z=117

z=117/9

z=13

C)8y=96

y=96/8

y=12

D) 7w+5=82

7w=82-5

7w=77

w=77/7

w=11

Answer 2

Respuesta:

¡Hola!

$5x + 5 = 20\\5x = 20-5\\5x = 15\\x = \frac{15}{5} \\x = 3$

$9z - 9 = 108\\9z = 108 + 9\\9z = 117\\z =\frac{117}{9} \\z = 13$

$8y = 96\\y = \frac{96}{8} \\y = 12$

$7w + 5 = 82\\7w = 82 - 5\\7w =77\\w =\frac{77}{7} \\w = 11$

Espero que te sirva :)
