Question

What is x+y=10;y=x+10

Answer 1

[ Answer ]

`\boxed{\bold{X \ = \ 0, \ Y \ = \ 10}}`

[ Explanation ]

• System Of Equations
  `\bold{\left \{ {X \ + \ Y \ = \ 10} \atop {Y \ + \ X \ = \ 10}} \right.}`

-----------------------------------

• [Substitute] Y = X + 10

`\bold{\begin{bmatrix}x+x+10=10\end{bmatrix}}`

• Isolate x for x + x + 10 = 10: x = 0

For y = 10

Substitute x = 0

Y = 0 + 10

0 + 10 = 10

y = 10

• Solutions

X = 0

Y = 10

`\boxed{\bold{[] \ Eclipsed \ []}}`
