Janes age is 5 years less than 3 times her brothers age. Janes age is 11 minus her brothers age. How old is Jane?
2 answers:
You did not specify the brother's age, so I make a expression, <em>b</em> as the variable.
(3<em>b</em> + 5) - 11
Now do that with the brother age instead of the variable.
(3b + 5) - 11 = 3
you first add 3 and 5 which equals 8 ten you subtract 11 and 8 which equals 3, so jane is 3 years old

Answer:
x²=5-x
x²+x-5=0
1x²+1x²-5=0
[ax²+bx²+c=0]
∆=b²-4ac
∆=1²-4(-5)(1)=1+20=21
x=(-b±√∆)/2a
x=(-1±√21)/2
meaning:
x=(-1+√21)/2 or x=(-1-√21)/2
