X = -12
First is moving the -15 over with the 93 by adding it on both sides. The equation will look like this: -9x = 108
Then you’ll divide by -9 and get x = -12
245.34 is 174% of 141 :)
(1.74*141=245.34)
It helps to remember that "of" in math means to multiply. That's helped me for years.
If yo have |a|=b solve for a such that a=b or a=-b
divideboth sides by 2
|x|=3/2
x=3/2 or -3/2
Answer:
y = − 1
Hope this helps!
Step-by-step explanation:
Alright so this is our equation:
y − 3 = 2 ( x − 1 )
We will substitute:
x = − 1
So now our equation looks like this:
y − 3 = 2 ( −1 − 1 )
Now we will get rid of the parentheses:
y − 3 = − 2 − 2
Solve the left side:
y − 3 = − 4
Now add 3 on both sides to find out what y is:
y − 3 = − 4
+3 +3
Add:
y = − 1
Yay! We found our answer! Nice job everyone!
