In the expression 2x plus 3 equals 9. What is the value of x?
You first must use SADMEP or PEMDAS backwards. (parentheses, exponent, multiply and divide, add and subtract) With this information you must ether add or subtract first 2x + 3 = 9 (Now, subtract 3 from each side of the equation) 2x + 3 - 3 = 9 - 3 (and the result is...)2x = 6 (whatever you do to one side of the equation you must do to the other.) 2x = 6 (Divide both sides by 2)2x/2 = 6/2 (and you get...) x = 3
