Answer:
the answer to x+(-9)=32 is x=41
X+y = 12
x-y = 3
x = 3+y
Substitute it in 1st equation,
3+y+y=12
2y = 9
y = 4.5
Substitute it in 1st eq.,
x = 12-4.5 = 7.5
So, the two numbers are 7.5 & 4.5
Hope this helps!
Answer:
log9
Step-by-step explanation:
Using the rules of logarithms
logx + logy = log(xy)
logx - logy = log()
log ⇔ nlogx
Given
2(log18- log3) + log
= 2(log( ) ) + log
= 2log6 + log
= log6² + log
= log36 + log
= log( 36 × )
= log9
