How do you work out the problem 72 divided by 2 plus a equals 40?
72/2 + a = 40 multiply both sides by 2 2(72/2 + a) = (40)2 72 + 2a = 80 subtract 72 from each side 72 - 72 + 2a = 80 - 72 2a = 8 divide both sides integers by 2 (2/2)a = 8/2 a = 4 ------------check in original equation 72/2 + (4) = 40 36 + 4 = 40 40 = 40 ----------------checks ------------------------------------------------------------------------if you meant 72/(2 + a) = 40 multiply through by 2 + a 72 = 80 + 40a subtract 80 from each side - 8 = 40a divide each side by 40 - 8/40 = a - 1/5 = a ----------------------check in original equation 72/(2 + [- 1/5]) = 40 now 2 is 10/5 72/(10/5 + [- 1/5]) = 40 72/(9/5) = 40 72/(9/5) is the same as 72 * 5/9 360/9 = 40 40 = 40 -------------------------------checks either way
