Answer 1

x= -40

Hope this helps!!

Answer 2

d.) x = -40

Explanation:

`\sf Given \ equation: \ log_(5) (-3x+5) = 3`

Solving steps:

`\rightarrow \sf log_(5) (-3x+5) = 3`

If logₐ(b) = c then b = aᶜ

`\rightarrow \sf -3x+5 = 5^3`

`\rightarrow \sf -3x+5 = 125`

`\rightarrow \sf -3x = 125-5`

`\rightarrow \sf -3x = 120`

`\rightarrow \sf x = 120/-3`

`\rightarrow \sf x = -40`
