No?

shelby1290 · Answer

so would it be the manuel way (long way)

shelby1290 · Answer

that involves dividing both sides

anonymous · Answer

no. there is no long way this only takes 1 step to solve

ganpat · Answer

u can try that.. Just u have messed up the numbers.. Try and Re arrange !!

shelby1290 · Answer

5x-4x

shelby1290 · Answer

that answer divided by 7

shelby1290 · Answer

sorry i just really do suck at this unit

ganpat · Answer

perfect !!.. thats solution for x !!

anonymous · Answer

why are you dead set on dividing by 7 just use inverse operations on the 4x across the = sign and you have your answer

shelby1290 · Answer

dont you have to divide by 7 ?

shelby1290 · Answer

but isnt that what i just did

ganpat · Answer

oops.. i read it wrong.. divide the 7 by answer.. as @lonnie455rich  said..

shelby1290 · Answer

so the answer is 7 divided by 5 ?

shelby1290 · Answer

x=1.4?

ganpat · Answer

No !!

5x = 4x + 7
5x - 4x = 7

1x = 7

x = 7/1

therefore, x = 7

ganpat · Answer

can u just tell me, how did u get x = 1.4 ?? M just Curious.. :) :D

anonymous · Answer

remember the 1 is understood by x so we just don't even write it so its just 
x=7 after you subtract the 4x from both sides using inveroperations

shelby1290 · Answer

ohhh okay
wait what if i had to do 11s+25=54+25+2s

anonymous · Answer

inverse operations that is all you need to know when solving MOST types of equations

shelby1290 · Answer

7 divided by 5

shelby1290 · Answer

sorry i did some extreme weirdness

shelby1290 · Answer

im just not so great at math

ganpat · Answer

put all s terms on one side and rest all terms on other side.. (Try solving)

anonymous · Answer

first thing I would do on that one is examine the 25s. 
then I would get your variable on 1 side then I would use inverse operations to finish solving

ganpat · Answer

hey relax !! m just kidding man.. u doing good.. u need to practise a little :)

shelby1290 · Answer

@lonnie455rich by inverse you mean opposite ? right

anonymous · Answer

yes like
+ -
/ * 
radical powers
exponential log
derivative integral 
and so on

shelby1290 · Answer

ahh okay and collect like terms? or just divide by 11

anonymous · Answer

don't divide by 11 until you get all your variables together. and get your contants all on the same side

shelby1290 · Answer

so ... 11s+2s=25-54+25

shelby1290 · Answer

wow. you messed up signs or something here
