Answer:
x =
Step-by-step explanation:
given
4 - ax = 2 ( isolate the term in x by subtracting 4 from both sides )
- ax = 2 - 4 = - 2 ( divide both sides by - a )
x = =

Answer:
x = 17
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is
x² = 15² + 8² = 225 + 64 = 289 ( take square root of both sides )
x = = 17
