5x + 5x-1 = 675⇒5x - 5x5 = 675⇒5x1 + 15 = 675⇒5x × 65 = 675⇒5x = 625⇒5x = 54⇒x = 4 More

Answer 2

Step-by-step explanation:

5^x+5^x-1=750

We move all terms to the left:

5^x+5^x-1-(750)=0

yWe add all the numbers together, and all the variables

5^x+5^x-751=0

We move all terms containing x to the left, all other terms to the right

5^x+5^x=751

or

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

5*x+5*x-1-(750)=0

Solve : 10x-751 = 0

Add 749 to both sides of the equation :

10x = 751

Divide both sides of the equation by 10:

x = 751/10 = 75.1
