Answer:
x = 14
Step-by-step explanation:
-2(x-5)-4=-22
Distribute
-2x +10 -4 = -22
Combine like terms
-2x+6 =-22
Subtract 6 from each side
-2x+6-6 = -22-6
-2x = -28
Divide each side by -2
-2x/-2 = -28/-2
x = 14
These are all possible combinations:

Answer:
r = x/n
Step-by-step explanation:
Solve for r:
x/r = n
Take the reciprocal of both sides:
r/x = 1/n
Multiply both sides by x:
Answer: r = x/n
