You can solve this two ways:
One is by substituting in the numbers until you get 15=15.
6(0)-9=15
0-9=15
-9=15
6(1)-9=15
6-9=15
-3=15
6(2)-9=15
12-9=15
3=15
6(3)-9=15
18-9=15
9=15
6(4)-9=15
24-9=15
15=15
Solution is x=4
or you can find the value of x
by first adding 9 to both sides to get x by itself
6x-9=15
6x=24
Then divide by 6
x=4
Answer:
4--2/4--4
6/8=3/4
y=3/4 x +c
4=3/4(4)+c
4=3+c
4-3=c
1=c
y=3/4x+1
Step-by-step explanation:
Answer:
<h2>x = 6</h2><h2 />
Step-by-step explanation:
4x = 30 - x
5x = 30
x = 30/5
x = 6
Answer: -8 and -4
This is something you do through trial and error. Making a list or a table like shown below might help.
Answer:
e
Step-by-step explanation:
If you divide 36 by 12, you get 3.
For this to work, whatever the white wax is, it needs to be 3 times as more as 5.
5x3=15
