I don't get this can u give me an example of what i should do ?
some one help me with the 20 question I need to check my
awnser
Which ones don't you get?
mainly 16 and 17..
oops srry that's me above forgot to type in gabby srry
oh wait 17 is <8 /)_- durr
Sure! Let's take the first question as an example.
Question 1: –9p – 17 = 10
To solve this equation, we need to isolate the variable "p" on one side of the equation by performing operations to both sides of the equation. Here's the step-by-step solution:
1. Start by moving the constant term (-17) to the other side of the equation by adding 17 to both sides:
–9p - 17 + 17 = 10 + 17
–9p = 27
2. Next, divide both sides of the equation by the coefficient in front of "p" (-9) to find the value of "p":
–9p / -9 = 27 / -9
p = -3
So, the solution to the equation –9p – 17 = 10 is p = -3.
Now you can apply the same steps to solve the other questions. Remember, the goal is to isolate the variable to find its value. Good luck!
