Answer:
x=5
Step-by-step explanation:
4x+8=2x+3x+3
2x+3x=5x
4x+8=5x+3
-4x
8=1x+3
-3
5=1x
5/1
x=5
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.)
