Answer:

The value of -18x + 30y is -27

Explanation:

Algebraic Expressions

It's given that:

6x - 10y = 9

We are required to find the value of

-18x + 30y

The easiest way to solve the problem is to visualize that:

-18x = -3(6x)

30y = -3(-10y)

This means that the second expression is equal to the first expression multiplied by -3, thus:

-18x + 30y = -3(6x - 10y) = -3*9 = -27

The value of -18x + 30y is -27
