Answer:
The value of -18x + 30y is -27
Step-by-step 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
