---
a=1/2b+4
a-4b=-17
---
put the system of linear equations into standard form:
---
x = a
y = b
---
x - 0.5y = 4
x - 4y = -17
---
copy and paste the above linear system in standard form into this matrix-method solver:

---
solution:
x = a = 7
y = b = 6
---
graph:
---
x - 0.5y = 4
x - 4y = -17
---
x - 4 = 0.5y
x + 17 = 4y
---
2x - 8 = y
0.25x + 4.25 = y
