Question

Solve for y: ax + by = c

Answer 1

\[ax+by=c\]
\[by = c-ax\]
\[y=\frac{c-ax}{b}\]

Answer 2

\[\huge{ax+by=c}\]
\[\huge{ax-ax+by=c-ax}\]What i did is just subtracted both sides by ax
\[\huge{by=c-ax}\]
\[\huge{\frac{by}{b}=\frac{c-ax}{b}}\]

Answer 3

what do you get now @Christian18m ?

Answer 4

Dont forget that :

\[\huge{a+b=c}\]
\[\huge{a+b-b=c-b}\]
\[\huge{a=c-b}\]also :
\[\huge{ab=c}\]
\[\huge{\frac{ab}{a}=\frac{c}{a}}\]
\[\huge{b=\frac{c}{a}}\]
