Instead of distributing 2, we can actually divide both sides by 2:
x - 1 = 2x - 11
Isolate x:
x = 10
Hai! So, I have all the math and explanations in the picture attached.
I forgot to add on there(and you'll see it) wen i subtract 3x and add 10 to the other side it cancels each other out. -3 + 3= 0 and -10 + 10 = 0. Etc.
Other than that, if you have any other questions, comment them down below. :)
That would be 13/10 or 1 3/10
Answer:
247.666667
Step-by-step explanation:
Divide 12 on both sides
ds/w=cd/12
now multiply ds on both sides
w=cd/12ds
