Answer: x = -45

Step-by-step explanation:

-9(x-5) = -10x

Use distributive property and multiply-9 thru the first parentheses set

-9x + 45 = -10x

45 becomes positive by multiplying two negative numbers together

Add 10x to both sides to isolate the x variable

-9x + 10x = x

Subtract 45 from both sides to move the number from left to right side of =

X = -45
