Question

Resolva (A) 8b-3=5b+6 (B). 2y+9=10-y ​

Answer 1

Resposta:

8b-3=5b+6

8b-5b=6+3

3b=9

b=9/3

b=3

2y+9=10-y

2y+y=10-9

3y=1

y=1/3

y= 0,333

acredito q seja isso

Answer 2

a) 8b - 3 = 5b + 6

8b - 5b = 6 + 3

3b = 9 (:3)

b = 3

b) 2y + 9 = 10 - y

2y + y = 10 - 9

3y = 1

y = 1/3

Bons estudos!.
