28+2\times 5x=7
Multiply both sides of the equation by 12, the least common multiple of 3,6,12.
28+10x=7
Multiply 2 and 5 to get 10.
10x=7-28
Subtract 28 from both sides.
10x=-21
Subtract 28 from 7 to get -21.
x=\frac{-21}{10}
Divide both sides by 10.
x=-\frac{21}{10}
Fraction \frac{-21}{10} can be rewritten as -\frac{21}{10} by extracting the negative sign.
