4M + 5 = 9Subtract 5 from both sides: 4M = 4Divide both sides by 4: M = 14M + 5 = 9Subtract 5 from both sides: 4M = 4Divide both sides by 4: M = 14M + 5 = 9Subtract 5 from both sides: 4M = 4Divide both sides by 4: M = 14M + 5 = 9Subtract 5 from both sides: 4M = 4Divide both sides by 4: M = 1
x - 2y = 4 Add 2y to both sides: x = 4 + 2y Subtract 4 from both sides: x - 4 = 2y Divide both sides by 2: (x - 4)/2 = y or y = 0.5x - 2
