Find the length of LO if 6x  2 = LM, MO = 10, and LO = 11X  7 LO is a straight line:
6x  2 + 10 = 11x  7 {LM + MO = LO} 6x + 8 = 11x  7 {combined like terms} 8 = 5x  7 {subtracted 6x from both sides} 15 = 5x {added 7 to both sides} x = 3 {divided both sides by 5} LO = 6x  2 = 6(3)  2 {substituted 3, in for x, into 6x  2} = 18  2 {multiplied 6 by 3} LO = 16 {subtracted} © Algebra House
