Answer:
x = 3
Step-by-step 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.
