Step 1: Simplify both sides of the equation.
x−7=15+3x
x+−7=15+3x
x−7=3x+15
Step 2: Subtract 3x from both sides.
x−7−3x=3x+15−3x
−2x−7=15
Step 3: Add 7 to both sides.
−2x−7+7=15+7
−2x=22
Step 4: Divide both sides by -2.
−2x/−2=22/−2
x=−11
Answer:
A and B

using the law of exponents
•
=
, hence
=
→ A
note that (- 3)² = 9 = 3², hence
= (3²)³ =
→ B
