Question

Which of the equations below is equivalent to;
`18(1/9x + 1/3y) = 15`
A. `2x + 6y = 15`
B. `4x + 6y = 270`
C. `x + 3y = 15`
D. `1/9x + 1/3y = 270`

Answer 1

\[18(\frac{ 1x }{ 9 } + \frac{ 1y }{ 3 }) = 15\]

\[18(\frac{ x }{ 9 } + \frac{3y }{ 9 }) = 15\]

\[2(\frac{ x + 3y }{ 1 }) = 15\]

\[2(x + 3y) = 15\]

\[2x + 6y = 15\]

Understood? :)
Ask if you did not. :D
