Another maths homework question please

[wineoclockthanks]

The answer we're getting doesn't match the (supposed!) correct answer.

Any help, very gratefully received.

8x = 37 ?
X = 37/8 ?

add 2x to each side
8x + 19 = 56
take 19 from each side
8x = 37 (!) (could well be a typo in question)
divide each side by 8
x = 4 5/8 = 4.675

SORRY 4.625 no 675

That's the answer we are getting but apparently the answer is 3!

(Which is the same as the number of meltdowns we've had so far

Well, yeah, what Lweji said.

What's the supposed correct answer?

I was also guessing typo.

The answer is wrong.

There's a typo then.

Have you written it down correctly?

6x +19=56-2x
6x+2x=56-19
8x=37
×=37/8

I got the same as TeenTimesTwo

x = 4.625

Is it a typed or written question?

Phew, I'm glad it's not just us who can't work it out. We've managed the other 35 questions but poor perfectionist, overtired DS (and his very similar mum), are stumped.

Thanks all.

The answer obviously isn't 3 as 37 does not equal 50.

It's typed Pixie

That's what's nice about algebra, you know if you have the right answer as you can plug it (substitute it) back into the original equation.

I wrote it out cos couldn't work out how to make the x not look like the multiplication sign

56-(2×3)=50

It does not equal (6×3) + 19, which is 37.

Is this a trick question so that all the children don't come in with the answers copied out?

Teen at the moment, there is NOTHING nice about algebra

wine apart from trying to prove the book right rather than having faith in yourselves, there isn't a problem.

Algebra is like old fashioned weighing scales.
You have to keep the scales equal (level)
Whatever you do on one side, you have to do to the other.
So e.g. to get rid of the -2x on the RHS you have to add 2x, so you have to add 2x on the LHS too. etc.

Everything else in equation solving and formula manipulation goes from that principle.

Can you take a picture of the question ?

It's obviously a typo. Solving it doesn't give 3 and if you substitute x with 3 is not correct. A picture might help to figure out where the typo is but it's pretty irrelevant really.

Yeah the answer is 37/8

There is no way its 3

The answer was a bloody typo!! Not impressed.

Thanks for everyone's help

What age is this out of interest?
