Answer:
is the answer
Step-by-step explanation:
7(5x+9)=12+−1(x+9)(Distribute the Negative Sign)
7(5x+9)=12+−x+−9
(7)(5x)+(7)(9)=12+−x+−9(Distribute)
35x+63=12+−x+−9
35x+63=(−x)+(12+−9)(Combine Like Terms)
35x+63=−x+3
Add x to both sides.
35x+63+x=−x+3+x
36x+63=3
subtract 63 from both sides.
36x+63−63=3−63
36x=−60
Divide both sides by 36.
-5/3 is the answer.
ik this doesnt make any sense but hope this helps
So basically, think of a ratio as a fraction for these problems. You see the 2 numbers and you put the first one as the numerator and the second as your denominator. For example:
5 to 10
We would change this into:
Because the problem says to simplify, we can divide both sides by 5 and simplify it into:
If the problem says 5:10 instead of "5 to 10" it's the same problem just with different wording. If the numbers are labeled, the you can write the labels next to the number it corresponds with.
If you have any questions, feel free to ask down in the comments, I'll be happy to work with you!
