-9x+28=2\left(4\times 7+4\right)
Multiply both sides of the equation by 14, the least common multiple of 14,7.
-9x+28=2\left(28+4\right)
Multiply 4 and 7 to get 28.
-9x+28=2\times 32
Add 28 and 4 to get 32.
-9x+28=64
Multiply 2 and 32 to get 64.
-9x=64-28
Subtract 28 from both sides.
-9x=36
Subtract 28 from 64 to get 36.
x=\frac{36}{-9}
Divide both sides by -9.
x=-4
Divide 36 by -9 to get -4.
