2x + 2y = 26
x = 5
---
copy and paste the above linear system in standard form into this matrix-method solver:
https://sooeet.com/math/system-of-linear-equations-solver.php
---
solution by matrix method:
x = 5 cm
y = 8 cm
---
system matrix
2 2
1 0
---
inverse of system matrix
0 1
0.5 -1
---
determinant of system matrix = -2
---
now by substitution method:
---
2x + 2y = 26
---
x = 5
---
2(5) + 2y = 26
10 + 2y = 26
2y = 16
---
y = 8
---
solution by substitution method:
x = 5 cm
y = 8 cm
---
both methods agree.
