Ok so first you move them together so:
9x-3x=-36
6x=-36
x=

Then divide to get: -
6
Your answer would be
A
Log xy/4 =
log xy - log 4 =
log x + log y - log 4
1 Answer
1.multiply the First terms. x⋅x=x2.
2.multiply the Outside terms. x⋅10=10x.
3.multiply the Inside terms. −10⋅x=−10x.
4.multiply the Last terms. −10⋅10=−100.
5.add all of the answers together. x2+10x−10x−100.
6.combine like terms. x2+10x−10x−100. =x2−100.
3÷2= 1.5
To make sure if it's correct,
1.5
