Question

Solve the equations
8y - 1 = -17

t/5 + 7 =-1

Answer 1

Let's solve each equation one by one.

1. For the equation \( 8y - 1 = -17 \):

First, add 1 to both sides:
\[
8y - 1 + 1 = -17 + 1
\]
This simplifies to:
\[
8y = -16
\]

Next, divide both sides by 8:
\[
y = \frac{-16}{8} = -2
\]

Thus, \( y = -2 \).

2. For the equation \( \frac{t}{5} + 7 = -1 \):

First, subtract 7 from both sides:
\[
\frac{t}{5} + 7 - 7 = -1 - 7
\]
This simplifies to:
\[
\frac{t}{5} = -8
\]

Next, multiply both sides by 5:
\[
t = -8 \times 5 = -40
\]

Thus, \( t = -40 \).

Final answers:
- \( y = -2 \)
- \( t = -40 \)
