Let
x--------> the number
we know that
Multiply by both sides
therefore
the answer is
1 U.S. dollar = 0.15 Chinese yuan
6.84 U.S. dollars = 1 Chinese yuan
1 U.S. dollar = 6.84 Chinese yuan
Answer:

Answer:
All real numbers
Step-by-step explanation:
2(x + 1) = 2x + 2
2x + 2 = 2x + 2
2x + 2 - 2x - 2 = 2x + 2 - 2x - 2
0 = 0
All real numbers
Answer:
0
Step-by-step explanation:
Step 1: Distribute
2(x+1) =2x + 2
Step 2: Solve
2x +2 = 2x +2
-2 -2
=2x = 2x
-2x -2x
=0
40.00 - 19.50 = 20.50
20.50 ÷ by 2 = 10.25
each video cost
Geno now wants to write an equation to solve the problem. He let g = cost of a video game.
Which equation can be used to find the cost of each video game?
A. 2g = 19.5
B. 2g + 40 = 19.5
C. 2g –19.5 = 40
