Step-by-step explanation:
Given
2(3x - 5) = 6x + 8 ← distribute left side
6x - 10 = 6x + 8 ( add 10 to both sides )
6x = 6x + 18 ( subtract 6x from both sides )
0 = 18 ← not possible
This indicates the equation has no solution
Answer:
He did not check for extraneous solutions.
Step-by-step explanation:
He solved the equation correctly and obtained solutions -2 and -5, but there is one final step he did not do.
Every time you square both sides of an equation to solve it, you must check for extraneous solutions. If he did, he would have eliminated x = -5.
Answer: He did not check for extraneous solutions.

Answer:
Mia scored 6 baskets Last Saturday.
Step-by-step explanation:
Let:
Mia made score of baskets on Last Saturday = x
Mia made score of baskets yesterday = 3x (Mia made three times as many baskets in yesterday’s basketball game as she did last Saturday. three times means multiply 3 with score of Last Saturday baskets, i.e. x)
Total score of baskets = 24
We need to find How many baskets did Mia score last Saturday?
We can write:
<em>Total Score = Score on Last Saturday + Score yester</em>day
Solving this equation we can find value of x:
So, we get value of x = 6
Mia made score of baskets on Last Saturday = x = 6
Mia scored 6 baskets Last Saturday.
