y-5/3 = 1 A) –2 B) 8 C) 18 D) 6 Can you tell me how to do it for future problems thanks!
add \(\Large{\frac{5}{3}}\) both sides :)
B) 8
In future problems if u see any question similar to this then put all constants at one sides & all variables at one side by reversing their signs :)
if you added the fraction to both sides wouldn't y = a fraction ;o? or decimal
2x+3=5 Put all variables and their coefficients at one side & constants at one side by reversing their signs 2x=5-3 2x=2 x=1
Is this: \[\frac{y-5}{3}=1\]Or\[y-\frac{5}{3}=1\] ?
B) 8
its the first one @Xishem
If there is a plus sign then it will change to (minus) & if it is (minus) then it will change to (plus). If there is a multiplication sign then it will change to division & if division it will change to multiplication.
would the answer still be one as the first problem in @xishems comment
\[\frac{y-5}{3}=1\]\[(3) \cdot \frac{y-5}{3}=1 \cdot (3)\]\[(5)+y-5=3+(5)\]\[y=8\]In an equation, if you perform the same operation to both sides, the equation stays true.
Notice how in the second line, the 3s on the left side cancel out and become y-5. And the +5 and -5 cancel out in the third line to make y. In solving for variables, you'll always want to perform operations such that this "cancellations" occur.
o ty
if two numbers times or divide each other they cancel out?
