---
u=v
9u=3v-36
---
put the system of linear equations into standard form:
---
x = u
y = v
---
x = y
9x = 3y - 36
---
x - y = 0
9x - 3y = -36
---
copy and paste the above linear system in standard form into this matrix-method solver:

---
solution:
x = u = -6
y = v = -6
---
graph:
---
y = x
3y = 9x + 36
y = 3x + 12
