Question

Ifn=10, E(X-6) = 30, find x.​

Answer 1

Solve by Substitution

Let's solve your system by substitution.

n=10;2.718282(x−6)=30

Rewrite equations:

n=10;2.718282x−16.309691=30

Step: Solven=10for n:

n=10

Step: Substitute10fornin2.718282x−16.309691=30:

2.718282x−16.309691=30

2.718282x−16.309691=30

2.718282x−16.309691+16.309691=30+16.309691(Add 16.309691 to both sides)

2.718282x=46.309691

2.718282x

2.718282

=

46.309691

2.718282

(Divide both sides by 2.718282)

x=17.036382

Answer:

n=10 and x=17.036382
