7x-3y-43=0
3x+7y-35=0
---
put the system of linear equations into standard form
---
7x - 3y = 43
3x + 7y = 35
---
copy and paste the above standard form linear equations in to this solver:
https://sooeet.com/math/system-of-linear-equations-solver.php
---
solution:
x = 7
y = 2
---
by elimination:
---
7(7x - 3y = 43)
3(3x + 7y = 35)
---
49x - 21y = 43*7
9x + 21y = 35*3
---
add the two equations:
---
58x = 43*7 + 35*3
x = (43*7 + 35*3)/58
x = 7
---
3x + 7y = 35
3*7 + 7y = 35
7y = 35 - 3*7
y = (35 - 3*7)/7
y = 2
---
solution by elimination:
x = 7
y = 2
