Question

Can somone help me solve this please,
P = 4(3a – b) for a in terms of P and b.

anonymous · Answer

4 times 3 = 12a 
a times b = 4b
12a-4b

anonymous · Answer

first of all multiply 4 on the right side
P=12a-4b
now add 4b to the both sides

p+4b=12a-4b+4b
+4b and -4b get cancelled on the right side
it becomes 
p+4b=12a

i hope you can do this now !!

ok i can set it
you can add 3 to the both sides it will becomes

$$\Large |2x+7|>13$$
brb !!

anonymous · Answer

ok its is absolute value. it has two values
you need to solve the following two inequalities
2x+7>13
and
2x+7<-13
can you solve these ?
