Question

What is the value of 3x – 4y + z when x = 8, y = 2 and z = -6?

Answer 1

`3(8) - 4(2) + ( - 6) \\ \\ 24 - 8 - 6 \\ \\ 16 - 6 \\ \\ 10`

Answer 2

Given~

• x = 8

• y = 2

• z = -6

Let's Solve~

`\: \: \: \: \: \: \: \: \: \: \: \: \sf \: 3x - 4y + z`

`\: \: \: \: \sf \: 3( 8 ) - 4 ( 2 ) + ( -6 )`

`\: \: \: \: \: \: \: \: \: \: \: \sf \: 24 - 8 - 6`

`\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \sf \: 16 - 6`

`\: \: \: \: \: \: \: \: \: \: \: \: \: \sf \: \: \: \: \: \: \: \: \: \underline{ 10}`
