This equation can be solved graphically by plotting the equations
  f(x) = 3^x
and
  g(x) = 5x-1.

The x-coordinate of the point(s) of intersection is the solution.

_____
On my graphing calculator, I find it easier to locate x-intercepts, so I would rewrite the equation as
  3^x -(5x -1) = 0
and plot the function
  h(x) = 3^x -(5x -1)
The x-intercept(s) would be the solutions. (There are two: x≈0.577, x=2.)

Find the value of x and find whether the angles or supplementary or complementary.
Alborosie

Answer:

1) x = 31

2) Both angles add up to be a supplementary angle (an angle who's sum is 180° altogether).

Step-by-step explanation:

1) Since both angles add up to be a supplementary,

→ equation 1 + equation 2 = 180

→ (3x + 25) + (2x) = 180

Solving by applying algebra will give the answer "x = 31".

Hope this helps!
