Of Janet’s two solutions, both x=5 and x=-2 are correct because both x=-2 and x=5 are extraneous solutions
<h3>Logarithmic function</h3>
Given the log function expressed as:
log(x-3) + logx=1
According to the law of logarithm, addition becomes product to have:
log x(x -3) = log₁₀10
x² - 3x = 10
x² - 3x -10 = 0
x² - 5x + 2x - 10 = 0
x(x-5) + 2(x-5) = 0
(x+2)(x-5)=0
x = -2 and 5
Of Janet’s two solutions, both x=5 and x=-2 are correct because both x=-2 and x=5 are extraneous solutions

Jackie didn’t subtract 12 from 8 right, I think
Money : price = quantity
1) 3 : 0.5 = 6 Kg
2) 3 : 1 = 3 Kg
3) 3 : 1.5 = 2 Kg
4) 3 : 2 = 1.5 Kg
5) 3 : 3 = 1 Kg
