-7/9(x=3)=14

-7/9x-7/3=14 (distribute)
-7/9x=49/3 (add 7/3 to both sides)

x=-21 (divide 49/3 by -7/9)

you can check if its correct by substituting back into the original equation

\(-\frac{7}{9}(x+3)=14\ \ \ \ \ |multiply\ both\ sides\ by\ (-\frac{9}{7})\\\\(-\frac{ ot9^1}{ ot7_1})\times(-\frac{ ot7^1}{ ot9_1})(x+3)=-\frac{9}{7}\times14\\\\x+3=-9\times2\\\\x+3=-18\ \ \ \ \ |subtract\ 3\ from\ both\ sides\\\\\boxed{x=-21}\)
