Gracie Figueroa · Answer 1

Step-by-step explanation:

Ax - By = C

add BY : Ax - By+BY = C + BY

Ax = C + BY

1) case : A = 0 : 0x = C + BY

*) C + BY = 0 all reals x are solution

**) C + BY≠ 0 no solutions reals

2) case : A ≠ 0 single solution : x = (C + BY) / A

Answer: X = C+BY / A

Step-by-step explanation:

AX - BY = C

Add BY to bothside

AX - BY + BY = C + BY

AX = C + BY

Divide bothside by A

AX / A = C+BY / A

X = C + BY / A
