If you mean: 5u+10 = u+46 Then the value of u is 9
-10, -9 and -8
It is: 46 = 46 or 2x = 46
Suppose she travelled x hours on foot. Total time = 10 hours so she travelled (10-x) hours on horseback. Therefore, on foot she travelled 3*x miles and on horseback she went 7*(10-x) miles. In total, that is 3x + 70 - 7x = 70 - 4x The total distance travelled was 46 miles so that 70 - 4x = 46 Therefore 4x = 70-46 = 24 and so x = 24/4 = 6 hours.
