Answer
A solução da equação é y = -5.
Solution
Vamos resolver a equação:
3y - 1 - 9y = 29
1. Primeiro, combine os termos semelhantes:
3y - 9y = -6y. Assim, a equação fica:
-6y - 1 = 29
2. Em seguida, isole o termo que contém y adicionando 1 dos dois lados:
-6y = 29 + 1
-6y = 30
3. Por fim, divida os dois lados por -6 para encontrar y:
y = 30 / (-6)
y = -5
Portanto, a solução da equação é y = -5.

To solve the equation \( 3y - 1 - 9y = 29 \), first, combine like terms. This results in: \[ 3y - 9y - 1 = 29 \] which simplifies to: \[ -6y - 1 = 29 \] Next, add 1 to both sides: \[ -6y = 30 \] Now, divide by -6: \[ y = -5 \] So the solution is \( y = -5 \). If you want to double-check your solution, simply plug \( y = -5 \) back into the original equation to see if both sides are equal. This practice will help ensure you're on the right track! Solving linear equations can be a piece of cake with the right approach! Just remember to simplify step-by-step, and keep an eye out for those pesky signs – they can easily throw off your result if you're not careful!
