Answer:
3 is your answer for x
Explanation:
3x - 4 = 5
Isolate the x. Do the opposite of PEMDAS. Note the equal sign, what you do to one side, you do to the other.
First, add 4 to both sides
3x - 4 (+4) = 5 (+4)
3x = 5 + 4
3x = 9
Next, divide 3 from both sides
(3x)/3 = (9)/3
x = 9/3
x = 3
3 is your answer for x
