Question

Solve for x, y, and z,1 -6 -81 -72) 10 1 80 0 1 30

Answer 1

The system, it is standard form is

meaning

`y=8`

and

`z=3.`

With the value of y an z in hand, we now solve for x in the first equation

`x-6(8)-8(3)=-7`
`x=-7+48+24`
`\textcolor{#FF7968}{\therefore x=65.}`

Hence, the solution is

x = 65, y = 8, and z = 3.
