Question

Solve the proportion 2x + 1/ x + 1 = 2x/ x + 2

Answer 1

2x+1/x+1 = 2x/x+2

Bring the all the terms to one side

2x+1/x+1 - 2x/x+2 = 0

(2x+1)(x+2)-2x(x+1) / (x+1)(x+2) = 0

(2x^2+4x+x+2)-2x^2-2x / x^2+2x+x+2 =0

Cancel the possible terms

3x+2 / x^2+3x+2 = 0

 

Answer 2

Cross multiplication.
