1/x + 1/y = 8
x + y = 8
6/x + 12/y = 72n
Answer:x=-5 and x=3
Step-by-step explanation:
log(x^2-15)=log(2x)
Cancel log at both sides we get
x^2-15=2x
Collect like terms
x^2-2x-15=0
x^2-3x+5x-15=0
x(x-3)+5(x-3)=0
(x+5)(x-3)=0
x+5=0 x-3=0
x=-5 x=3
Step-by-step explanation:
standard form is given by Ax × By = C
hence the answer would be
5x + 8y = 24

Answer:
y=4-1/3x
Step-by-step explanation:
