The standard form is \(Ax+By=C\).

Multiply both sides of the equation by 3:

\(3(y)=3(\frac{2}{3x}+7)\)

\(3y=2x+21\)

Subtract 2x from both sides: \(3y−2x=2x+21−2x\)

\(3y−2x=21\)

\(−2x+3y=21\)

which is choice a.

a) \(2x + y = 11\)

\(x = 13 + y\)

b) \(2x = 11 - y\)

\(4x - y = 13\)

c) \(\displaystyle-\frac{{1}}{{2}}{x}-{y}=\frac{{3}}{{4}}\)

\(\displaystyle\frac{{3}}{{2}}{x}+{2}=-\frac{{7}}{{8}}\)

d) \(\displaystyle-{x}²+{y}={10}\)

\(x + y = 5\)
