Question

Which of the following values in the set below will make the equation 2x + 1 = 3 true?

{0, 1, 2, 3, 4}

Answer 1

just solve for x
2x + 1 = 3 --- subtract 1 from both sides
2x = 3 - 1
2x = 2 -- now divide both sides by 2
x = 1.....any other value for x will not be true

Answer 2

thank you wow ur good lol

Answer 3

you can even check it by subbing in 1 for x
2(1) + 1 = 3
2 + 1 = 3
3 = 3 (true)
