Answer 1

7x+2^2=25
We move all terms to the left:
7x+2^2-(25)=0
determiningTheFunctionDomain 7x-25+2^2=0
We add all the numbers together, and all the variables
7x-21=0
We move all terms containing x to the left, all other terms to the right
7x=21
x=21/7
x=3

Answer 2

7x + 2² = 25
7x + 4 = 25
7x = 21
x = 3
x is equal to three
