Algebra Help how do I work this out ???
Got an exam coming up next week and need to brush up on my maths skills how would i work this sum and sums like it out ? answer with a breakdown of the help would be great thanks.
find X if
5x - 5 = 4x + 12
find X if
5x - 5 = 4x + 12

so when rearranging would I just put the x from one side on the 5 or would I swap the 5 with the 4 so for eg
5x - 5x = 4 + 12
or
5x - 4x = 5 + 12
5x - 5x = 4 + 12
or
5x - 4x = 5 + 12
The one in bold is correct.

ok brilliant thanks for your help i'll try another practice one now
7z - 12 = 6z + 25
so i'd do 7z - 6z = 12 + 25
1z = 37
7z - 12 = 6z + 25
so i'd do 7z - 6z = 12 + 25
1z = 37
Correct
