(13 + x)/(50 - x ) = (2/1) Cross Multiply 2(50-x) = 1(13 + x) 100 - 2x = 13 + x add 2x to both sides 100 -2x + 2x = 13 + x + 2x 100 = 13 + 3x Subtract 13 from both sides 100 - 13 = 13 - 13 + 3x 87 = 3x divide both sides by 3 29 = x (13 + 29)/(50-29) = 42/21 = 2 to 1 ratio
The correct answer is 29 .
