Since you are solving for S, you need to single it out. Do this by adding 3 to both sides which eliminates the -3 and adds 3 to -5 giving you -2. Now S = -2
Answer:
x = -1
Step-by-step explanation:
2x - 7 = 9x
Subtract 2x from both sides: -7 = 7x
Divide both sides by 7: -1 = x
Now plug in 7 for every value of x in the original equation to make sure you are correct:
2(-1) - 7 = 9(-1)
-2 - 7 = -9
-9 = -9
I hope this helps!
Answer: Approximately -8.54
Explanation: use Pythagorean’s theorem.
