The solutions are $-\frac{2}{7}$ and $\frac{4}{5}$.
If a product is 0, one of the factors must be 0. Use the addition property of equality and the multiplication property of equality to solve for x. $7x+2=0\ or\ 5x-4=0$ $7x+2-2=0-2\ or\ 5x-4+4=0+4$ $7x=-2\ or\ 5x=4$ $7x\div7=\frac{-2}{7}\ or\ 5x\div5=4\div5$ $x=-\frac{2}{7}\ or\ x=\frac{4}{5}$
