Answer:
x = P/8
Step-by-step explanation:
The perimeter of the blueprint is given by the equation :
P = 8x
We need to solve the above equation for x.
Dividing both sides of the equation by 8.

Hence, the value of x is P/8
M is the independent variable
Replace the variables with numbers to find the expression
Answer:
x≤−13
Step-by-step explanation:
isolate the variable by dividing each side by factors that don't contain the variable
Answer: -2
Step-by-step explanation:
convert it to a equation:
7x+8=5x+4
move x's to a side and numbers to the other
2x=-4
divide by 2
x=-2
