8 = p - 5
Answer: p = 13
21 + y = 35
Answer: y = 14
6x = 54
Answer: x = 9
correct
looks good to me.
Good job.
To solve these equations, we need to isolate the variable on one side of the equation.
For the first equation, 8 = p - 5, we want to get rid of the -5 on the right side. We can do this by adding 5 to both sides of the equation:
8 + 5 = p - 5 + 5
This simplifies to:
13 = p
So the answer is p = 13.
For the second equation, 21 + y = 35, we want to isolate the y variable. To do this, we need to get rid of the 21 on the left side. We can do this by subtracting 21 from both sides of the equation:
21 - 21 + y = 35 - 21
This simplifies to:
y = 14
So the answer is y = 14.
For the last equation, 6x = 54, we want to isolate the x variable. To do this, we need to get rid of the 6 on the left side. We can do this by dividing both sides of the equation by 6:
6x / 6 = 54 / 6
This simplifies to:
x = 9
So the answer is x = 9.
