Equations with brackets
![Picture](/uploads/1/5/4/9/15493740/3180671.png)
Equations with brackets are very easy and simple when you get to know how to do it
firstly there are a couple of rules to go along by
for example 5(x+7)
this may a look a bit frightening but theres nothin' to it
all you have to do is times 5 with each value in the bracket
so inside the bracket i have x+7
which means i times 5 by x which equals 5x
then times 5 with the following value in this case in this case it's 7
5x7=35
now the two answers are 5x and 35 which form together to make 5x=35
5x=35 is the answer
but i was asked to simplify the answer to find out what x equals i would divide each value with 5 as there are 5 x's
therefore i get x=7
eg2) 5(x+7)=2x+41
1)solve the whats inside the bracket first
so 5x+35=2x+41
now the equation matches up to the normal way of working it out
so we can minus 2x on each side
5x+35=2x+41
-2x -2x
3x+35=41
next move 35 to the right side of 41
so it equals 5x+2x=41-35
7x=6 is the answer
worksheet
1)39x+4)=19
2)6(x+5)=54
3)4(x-3)=4
4)2(x=3)=10

iv'e put up the answers to see if you've got the correct of doing it!!
