C, because if it was D, they would be the same, which is A written in another format. Then process of elimination
15 is answer for the missing side
Answer:
x=−3.533333
Step-by-step explanation:
21
3
−1.5x=12.3
Step 1: Simplify both sides of the equation.
21
3
−1.5x=12.3
7+−1.5x=12.3
−1.5x+7=12.3
Step 2: Subtract 7 from both sides.
−1.5x+7−7=12.3−7
−1.5x=5.3
Step 3: Divide both sides by -1.5.
−1.5x
−1.5
=
5.3
−1.5
x=−3.533333
