39 - 17x = 12 Subtract 39 from both sides: -17x = -27 Divide both sides by -17: x = 27/17 = 1.5882...
9/13 because you divide by 3
69.23% 27 / 39 = 0.692308 * 100 = 69.2308
633.75 divide by 39 = 16.25
0.0013
39+27 = 66
Certainly I can: 100 ÷ 39 = 222/39 ≈ 2.564 However, 100 is not divisible by 39, that is 39 does not divide into 100 with no remainder.
you do 39 divide by 3 (3 divide by 39 same thing) which equals 13
39-12 = 27
100*27/39 = 69.2%
divide both numbers by 39/3 / 27/33/9do it again3/3 / 9/31/3 is simplest form
Original Equation: 4x + 9x = 39 Factor: x(4+9) = 39 Add: x(13) = 39 Divide: x = 3 Check: 4(3) + 9(3) = 12 + 27 = 39 = 39
