Question

3[10+(3y-1)-(4-y)]=5(y+10)
Equação de 1 grau

Answer 1

$3[10+(3y-1)-(4-y)]=5(y+10)$

$3[10+3y-1-4+y]=5y+50$

$3[4y+5]=5y+50$

$12y+15=5y+50$

$12y-5y=50-15$

$7y=35$

$y=\frac{35}{7}$

$y=5$

Answer 2

Olá, bom dia ☺

Resolução:

3[10+(3y-1)-(4-y)]=5(y+10)

3[10+3y-1-4+y]=5y+50

3[4y+5]=5y + 50

12y + 15 = 5y + 50

12y - 5y = 50 - 15

7y = 35

y=35/7

y=5

Bons estudos :)
