2) 3X+5=30
4) 3X+10=66
5)4X+20=100​

Answer 1

Resposta:

Explicação passo-a-passo:

1 -    $3x+6=50\\3x=50-6\\3x=44\\x=\frac{44}{3}=14,6667$

2 - $3x+5=30\\3x=30-5\\3x=25\\x=\frac{25}{3}=8,333$

4 - $3x+10=66\\3x=66-10\\3x=56\\x=\frac{56}{3}=18,6667$

5 - $4x+20=100\\4x=100-20\\4x=80\\x=\frac{80}{4}=20$

Answer 2

1) 3x= 50-6
x= 44/3
x= 14,6
2) 3x= 30-5
x=25/3
x= 8,3
4) 3x=66-10
x= 56/3
x= 18,6
5) 4x=100-20
x= 80/4
x=20
