This is for 30cm not 48 but you can find out how to do it. This is an example
Depends on what you are talking about, what is A,x,c and b.
If A is an invertible matrix and x,c,b are vectors of correct dimensions you get
Ax=b+c
x=A^(-1)(b+c)
if x is a variable and A,c,b are constants you get
Ax=b+c
x=(b+c)/A
Step-by-step explanation:
t = 4
u = 6 + 2
Find t - u
solu
t - u
= 4 - ( 6 + 2 ) = 4 - 8
Answer is -4
