5^(2x-1)+5^(x+1)=250
how do you solve?
thank you

x = 2

Step-by-step explanation:

Exponential Equations

Solve:

Separate each exponential:

Operating:

Multiplying by 5:

Rearranging:

Recall that:

Calling

Factoring:

There are two possible solutions:

y=25

y=-50

Since

y cannot be negative, thus:

The solution is:

x = 2

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)
