Answer:
No, Ivory is incorrect. The equation does have a solution, and the solution is x = -1.
Step-by-step explanation:
We try to solve the equation first.
2x + 2 = x + 1
We want all variables on the left side and all numbers on the right side.
Subtract x from both sides.
x + 2 = 1
Subtract 2 from both sides.
x = -1
Check: Plug in -1 for x on both sides and see if it makes a true statement.
2x + 2 = x + 1
2(-1) + 2 = -1 + 1
-2 + 2 = 0
0 = 0
0 = 0 is a true statement, so the solution x = -1 is the correct solution.
Answer: Ivory is incorrect. The equation does have a solution, and the solution is x = -1.

Answer:
I think 15.
Step-by-step explanation:
20 ÷ 5=4 and 5 × 3=15.
1. Find the Least Common Denominator (LCD) of

Method 1: By Listing Multiples<span>List out all multiples of each denominator, and find the first common one.
5: 5,10
2: 2, 4, 6, 8,10</span>
Method 2: By Prime FactorsList all prime factors of each denominator, and find the union of these primes.
5 : 5
2 : 2
Therefore, the LCD is 2 x 5 = 10
2. Make the denominators the same as the LCD

3. Simplify. Denominators are now the same

4. Join the denominators

5. <span>Simplify
