Question

Evaluate the expression for x=3 and y=5:(3y - 6)/x

Answer 1

Let's evaluate the expression by applying the Substitution Method.

Let's substitute x = 3 and y = 6 to the expression:

`\text{ }\frac{3y\text{ - 6}}{x}`

We get,

`\text{ }\frac{3y\text{ - 6}}{x}\text{ = }\frac{3(5)\text{ - 6}}{3}`
`\text{ = }\frac{15\text{ - 6}}{3}\text{ = }(9)/(3)`
`\text{ = }3`

Therefore, the expression (3y - 6)/x at x = 3 and y = 5 will give you a value of 3.
