Answer:
= 10 - 3n
Step-by-step explanation:
the terms 7, 4, 1, - 2 form an arithmetic sequence with n th term
=
+ (n - 1)d
where d is the common difference and
the first term
here d = - 2 - 1 = 1 - 4 = 4 - 7 = - 3 and
= 7, hence
= 7 - 3(n - 1) = 7 - 3n + 3 = 10 - 3n
Elimination, Multiply the second equation by -1, then add the equations together.
Answer:
1. move the constant to the right hand side to change its sign.
2.add the numbers.
3. using the absolute value definition rewrite the absolute value equation as two separate equations.
4.slove the equation for X
Step-by-step explanation:
it has two solutions
x=8
x= -9
the answer should be X1= 9, x2 =8
