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

Alenkasestr [34]

[ 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

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

6-1/3x=-1 How do I do this

I am Lyosha [343]

Im gonna assume you mean 6 - (1/3)x = -1. Your notation is not super clear. If so, solution is as follows:

6 - (1/3)x = -1 [subtract 6 from both sides]
-(1/3)x = -7 [multiply both sides by -3]
x = 21
