Scientific calculator question?

Question

how would you enter this problem in a scientific calculator?

2x + 3 = 8?

it keeps giving me the answer six, how can i put the = sign in without it solving the problem first?

i know the answer is not 6

Answer 1

well on my calc you press the buttons in this order: 2 (alpha) X + (sign) (there should be a button near the top under shift that shows the = sign) (alpha) = sign then click shift and solve then click = 2x. btw the answer is 2.5.

Answer 2

I don't really know how to do that on a calculator but it's really easy to solve by hand. You would subtract the 3 to the 8 and that equals 5. So now your problem looks like this: 2x=5

Now solve for x and in order to solve x you would have to divide everything by 2x because you just want x alone. When you divide everything by 2x, x=5/2 and that's the answer.

Answer 3

i dont think you can do it like that in the calculator straight out

heres how you WOULD do it tho

click [ y= ]

type in [2x+3]

click [table]

and where it sez that y=8, its gonna say what x= rite next to it

hope htat helped!

Answer 4

If you know the answer, why do you need a calculator?

Answer 5

i dont knoe exactly what you mean. are you trying to graph the equation? if u are u put 2x +3 and then press the shift button and the dot which should say space on top of it with a = sign and then 8.

hope this helps :)

Answer 6

put in 8 - 3 = / 2
