1.1349=267xDividing both sides by137,17=2xx=142.b+1b−1=56Multiplying both sides by 6(b-1),6b+6=5b−56b−5b=−5−6b=−113.b−1b+1=56Multiplying both sides by 6(b+1)6b−6=5b+56b−5b=5+6b=111. \frac{13}{49} = \frac{26}{7x}\\ \textsf{Dividing both sides by} \frac{13}{7},\\ \frac{1}{7} = \frac{2}{x}\\ x = 14\\ 2. \frac{b + 1}{b - 1} = \frac{5}{6}\\ \textsf{Multiplying both sides by 6(b-1)},\\ 6b + 6 = 5b -5\\ 6b - 5b = -5-6\\ b = -11\\ 3.\frac{b-1}{b+1} = \frac{5}{6}\\ \textsf{Multiplying both sides by 6(b+1)}\\ 6b-6 = 5b+5\\ 6b-5b = 5+6\\ b=111.4913=7x26Dividing both sides by713,71=x2x=142.b−1b+1=65Multiplying both sides by 6(b-1),6b+6=5b−56b−5b=−5−6b=−113.b+1b−1=65Multiplying both sides by 6(b+1)6b−6=5b+56b−5b=5+6b=11
