Question

Answer 1

Hi there, s-1/4-4/8=0. s-1/4-1/2=0. Lastly, s-3/4=0÷+3/4. Therefore, s=3

Answer 2

Simplify 4848 to 1212
s−14=12s−14=12
2 Multiply both sides by 44
s−1=12×4s−1=12×4
Simplify 12×412×4 to 4242
s−1=42s−1=42
Simplify 4242 to 22
s−1=2s−1=2
Add 11 to both sides
s=2+1s=2+1
Simplify 2+12+1 to 33
s=3s=3
