2 answers:
Answer:
C. Add 15 to both sides
Step-by-step explanation:
Given equation:
99x – 15 = 45
To solve:
<u>Step 1</u>: Add 15 to both sides:
⇒ 99x – 15 + 15 = 45 + 15
⇒ 99x = 60
<u>Step 2</u>: Divide both sides by 99:
⇒ 99x ÷ 99 = 60 ÷ 99
⇒ x = 60/99
⇒ x = 20/33
Answer:
Choice C: Add 15 to both sides.
Step-by-step explanation:
Given:
99x – 15 = 45
Aim:
To Find the first step.
Solution:
The first step will be Add 15 to both sides:
- 99x-15+15 = 45+15
- 99x + 0 = 65
- 99x = 60
Choice C is accurate.

EXTRA:
Let's solve the equation further.
Then transpose 99 to the RHS:
