4x + 35 = 49.9 so 4x = 49.9 - 35 = 14.9 => x = 14.9 / 4 = 3.725 => 7x = 7*3.725 = 26.075

You should use your calculator for such simple sums. It is far quicker and involves fewer key depressions than posting the question on WA. I could tell you the answer but how can you be sure that I did not make a mistake? Or that I am not messing about?
4/7 = 0.57145/9 = 0.5555so 4/7 is not equal to 5/9
77/7 - 7 = 11 - 7 = 4
If the hypotenuse is equal to 7 and one side is equal to 4, the third side is: 5.745
