2)Evaluate the right-hand side expression at the given value to get a number.
3)See if the numbers match.
Sorry if wrong
Answer:
2x+12=24
first you subtract 12 from both sides
2x+12=24
-12. -12
The 12-12 should cancel itself, the rest of the equation you bring down to get
2x=12 (because 24-12=12)
Now you have 2x=12.
you then divide 2x by both sides.
2x=12
/2x=/2x
The 2x/2x cancels itself out so you then solve for 12/2x.
For this you just divide 12/2 which is 6!
x= 6 is your final answer.
to check this equation you can plug your number back into x to see if it is true! 2(6)+12=24.
6 times 2 is 12 and 12+12 is 24 so your answer (6) is true!
hope this helps! :D
X1 = 0
X2 = 1
X3 = 7
I hope that helps!! :)
1615/170
We first need to convert this into a proper fraction. Which means that the denominator must be larger than the numerator for it to be proper. Also, since 1615 is BIGGER than 170, we will end up with a mixed fraction. A mixed fraction always has a whole number.
1615 can go into 170 how many times?
9 times
170*9 = 1530
Now subtract.
1615 - 1530 = 85
Now we have our mixed fraction: 9 85/170
Now we must simplify the fraction.
85/5 = 17
170/5 = 34
17/34 is the smallest possible fraction we can get.
9 17/34
