Question

X = 3
A = 6
Y = 4
Z = 3

3x - 6a 5z + 3y​

Answer 1

`3x-6a=-27`

`5z +3y=27`

Combined, these equations cancel out to equal zero.

Explanation:

Given:

`X = 3\\A = 6\\Y = 4\\Z = 3`

Find:

`3x - 6a\\5z + 3y`

1.
`3x-6a`

To find the value of
`3x-6a`, substitute 3 for
`x` and 6 for
`a`:

`3x-6a\\3(3)-6(6)\\9-36\\-27`

2.
`5z +3y`

To find the value of
`5z +3y`, substitute 3 for
`z` and 4 for
`y`:

`5z+3y\\5(3)+3(4)\\15+12\\27`
