What is the value of x if 4x + 3 = 23?
Try plugging each of the given choices as x in the expression 4x + 3 and see which one will give the value of 23. If we take x = 5, we have 5x4 equals 20, and 20 + 3 equals 23. Clearly, 5 is the correct answer.Another method would be to solve algebraically: 4x + 3 = 23; isolate the term with the x variable: 4x = 23 − 3 = 20; we then have: 4x = 20; divide both sides of the equation by 4 to get the value of x: 4x/4=20/4; this gives us the value of x:x = 5.
