not sure about #1 sorry

2. AB+BC=AC (add AB and BC to get AC)

9+BC=24 (substitutes the given numbers)

9-9+BC=24-9 (subtract 9 from both sides)

BC=15

3. AB+BC=AC

2x+4x=42

6x=42

6x/6=42/6

x=7

4. AB+BC=AC

3x-1+2x+4=38 (add 3x and 2 x and -1 and 4)

5x+3=38 (subtract 3 from both sides)

5x=35 (divide both sides by 5)

x=7
