Question 927946
12x+42y= -17
30x-18y=19
---
put the system of linear equations into standard form
---
12x+42y= -17
30x-18y=19
---
copy and paste the above standard form linear equations in to this solver:

---
solution:
x = 0.33333333
y = -0.5
---
by elimination:
---
18(12x + 42y = -17)
42(30x - 18y = 19)
---
18*12x + 18*42y = 18*(-17)
42*30x - 42*18y = 42*19
---
add the two equations:
---
18*12x + 42*30x = 18*(-17) + 42*19
(18*12 + 42*30)x = 18*(-17) + 42*19
x = (18*(-17) + 42*19) / (18*12 + 42*30)
x = 0.333333333333
---
12*(0.333333333333) + 42y = -17
y = (-17 - 12*(0.333333333333)) / 42
y = -0.5
---
solution by elimination::
x = 0.33333333
y = -0.5
