Hey, I'm not the greatest whizz kid at maths but i know my bit.

I've recently been having problems with Algebra, Well, To be honest i've never really grasped the true concepts of Algebra, I know a fair bit, Although i get kind of confused on a certain type of equation.

Eg. If X=9, Then what is 17X + 7.

 

If anyone can give me a brief explanation on how to solve these and what units to use, That would be awesome and would really help out when my SATS come along in May.

 

Thanks,

Ben.

160 is the answer

 

basically think of it like a puzzle your given 17x + 7 (the part of the puzzle that they gave you) and then they gave you another clue and thats x=9

 

so using order of operations: im assuming you know what that is you replace the x with (9) so this is what the equation will look like with the clue in it

 

17(9) + 7

 

Im also assuming that you know that two numbers side to side mean that you need to multiply them so the equation is

 

17x9+7

 

multiply 17 and 9 and you get 153

 

then whats left is

 

153+7

 

add them

 

160 (your answer)

Aah, Thank you very much Spikerz! All i did was 17+9+7 This clear shows how to work out those not-so-pesky Algebra questions.

Thanks!

Ben.
