Question

3x + 4 = 13 solve for X

Answer 1

x = 3

Explanation:

3x + 4 = 13

-4 -4

3x = 9

3 3

x = 3

Answer 2

x = 3

Explanation:

Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x. Do the opposite of PEMDAS.

First, subtract 4 from both sides:

3x + 4 (-4) = 13 (-4)

3x = 13 - 4

3x = 9

Next, divide 3 from both sides:

(3x)/3 = (9)/3

x = 9/3

x = 3

3 is your answer for x.
