So for me, how I would do it is move the variables and numbers to one side. So we have the equation 3x-3=2/5x+7. So you would subtract 2/5x to the left side and add 3 to the right side. The equation will then turn out to be 3x-2/5x=7+3. Much more easier right? So just simplify both side, and you will get 13/5x=10. In order to isolate x, you have to divide 13/5 in both side, leaving x= 3 11/13 or 50/13. You can always plug the answer back in to double check :)
Answer:
y=1
Step-by-step explanation:
Let's solve by opening the bracket first
-5-(15y-1)=2(7y-16)-y
Open the bracket
-5-15y+1=14y-32-y
Collect like terms
-5+1+32=14y-y+15y
-5+33=14y+14y
28=28y
Divide both sides by 28
y=1
Therefore the final answer is 1
Answer:
No.
Step-by-step explanation:
It does not pass the vertical line test, so the relation is not a function. This is because there are x-values that have several y-values. To be a function, a relation must have x-values that only have one y-value each.
Hope this helps!
Answer:
16
Step-by-step explanation:
7x+14=6x+30
Move x into one side and whole numbers to the other.
Solve like linear equation.
7x+14=6x+30
7x-6x=30-14
x=16
Answer:
Sugar:
Honey:
Sugar substitute:
Step-by-step explanation:
35 + 14 + 21 = 70
35 out of 70 = 50%
14 out of 70 = 20%
21 out of 70 = 30%
