1-r/1+r = 2/3
THAT IS NOT CORRECT EQUATION!!!
r/1=r
1-r/1+r=1-r+r=2/3
1=2/3 THAT IS NOT CORRECT
solving for r,,
(1-r)/(1+r) = 2/3
*do cross multiplication: (1+r) is multiplied by 2, then 3 is multiplied by (1-r):
3(1-r) = 2(1+r)
3 - 3r = 2 + 2r
*transpose similar terms to one side of equation (all terms with r on left side, and constants on right side):
-2r - 3r = 2 - 3
-5r = -1
r = 1/5
so there,, :)
To solve the equation 1 - r / 1 + r = 2 / 3, we can follow these steps:
Step 1: Remove the fractions by cross-multiplying:
(1 - r) * 3 = (1 + r) * 2
Step 2: Expand the expressions:
3 - 3r = 2 + 2r
Step 3: Move all the variables to one side of the equation, and the constants to the other side:
-3r - 2r = 2 - 3
Step 4: Simplify the equation:
-5r = -1
Step 5: Divide both sides of the equation by -5 to solve for r:
r = (-1) / (-5)
Step 6: Simplify the fraction:
r = 1/5
So the solution to the equation 1 - r / 1 + r = 2 / 3 is r = 1/5.
