s + 4 = 8

Question

s =

Answer 1

To solve the equation \( s + 4 = 8 \), you need to isolate \( s \).

Subtract 4 from both sides:

\[ s + 4 - 4 = 8 - 4 \]

This simplifies to:

\[ s = 4 \]

So, \( s = 4 \).

Answer 2

j - 1 = 1
j =

Answer 3

To solve the equation \( j - 1 = 1 \), you need to isolate \( j \).

Add 1 to both sides:

\[ j - 1 + 1 = 1 + 1 \]

This simplifies to:

\[ j = 2 \]

So, \( j = 2 \).
