The first step would be to simplify both sides of the equal sign as much as possible.
8x - 5 = -3(3 - 2x)
8x - 5 = -9 - (-6x)
8x - 5 = -9 + 6x
Next, you would need to combine like terms on both sides of the equal sign to one on one side of the equal sign and one on the other.
8x - 5 = -9 + 6x
2x - 5 = -9
2x = -4
Now, all you have to do is isolate the x. To do this, you would divide both sides by 2.
2x = -4
x = -2
I hope this helps!
Answer:
? what are the answers from 1 and 2?
Step-by-step explanation:
Answer:
23 degrees
Step-by-step explanation:
First, subtract 9 from 29 to find the temperature at 9 A.M. The temperature at 9 A.M. was 20 degrees. The temperature from 5 A.M. doubled to get to the temperature at 9 A.M., so divide 20 by 2. The temperature at 5 A.M. was 10 degrees. The temperature from midnight to 5 A.M. fell 13 degrees, so add 13 to get the temperature at midnight. 13+10=23. It was 23 degrees at midnight.
He is incorrect because he should have 6 factors of 9.
To simplify you use order of operations or PEMDAS
P- Parenthesis
E- Exponents
M- Multiplication
A- addition
S- Subtraction
8-6(3)+13
There's parenthesis so the first thing we have to do is multiply 6 by three which is 18 so then our expression is
8-18+13
since it's just subtraction and addition you can go in any order
8-31
-23
-23 is your answer
