Question

Hello,

so I been struggling with these problem for a while. I need someone to explain what I'm

doing wrong.

1.Solve the logarithmic equation

log₄(x-4) + log₄(x-4)=1

Solve the System of equation. For any dependent equation, answer in order pairs from using y as the free variable.

2.x² +y²=113

x+y=-15

3.2x-3y=-2

6x-9y=6

5x-2y=3

-20x+8y=-12

The way I did:

1. log₄(x-4)/(x-4)=1

(x-4)/(x-4)=4¹

x-4=4(x-4)

x-4=4x-16

x+4x=4-16

5x=-12

12/5

x=2.4?

2.-y= -15-x

x²+(-15-x)²=113
