Question

Given that x=1 and y=-2, evaluate the following expression: (2x-y)/(8x+3y).

Answer 1

To evaluate the expression (2x-y)/(8x+3y) with x=1 and y=-2, substitute the given values into the expression and simplify to get the result 2.

Step-by-step explanation:

To evaluate the expression (2x-y)/(8x+3y) with x=1 and y=-2, substitute the given values into the expression:

(2(1)-(-2))/(8(1)+3(-2))

Simplifying the expression:

(2+2)/(8-6)

Combining like terms:

4/2

Dividing:
