Respondam pfvr galera k

Answer 1

Resposta:

$y=\frac{38}{23}$

Explicação passo-a-passo:

$20-\frac{15y}{2}-4y\\-\frac{23y}{2}+20\\-\frac{23y}{2}\cdot \:2+20\cdot \:2=1\cdot \:2\\-23y+40=2\\-23y+40-40=2-40\\-23y=-38\\\frac{-23y}{-23}=\frac{-38}{-23}\\y=\frac{38}{23}$

Answer 2

Resposta:

38/23

Explicação passo-a-passo:

5(4-3y/2) - 4y =1

20 - 15y/2 -4y = 1

20 - 1 = 4y + 15y/2

19 = 23y/2

38 = 23y

y = 38/23
