By inspection, you can see that adding either 3x or 4x to y yields the same result of 7, meaning that x must be 0. If x is 0, y must be 7, meaning that this equation has only one solution. Hope this helps!

Answer:

See Explanation

Step-by-step explanation:

$let \: y = { \sin}^{ - 1} (0) \\ \\ \therefore \: \sin \: y = 0 \\ \\ \therefore \: \sin \: y = \sin \: 0 \degree\\( \because \: \sin \: 0 \degree= 0) \\ \\ \therefore \: y \: = 0 \degree \\ \implies \: { \sin}^{ - 1} (0) = 0 \degree \\ \\ in \: the \: same \: way \\ \\ { \sin}^{ - 1} (0) = 180 \degree \\ \\{ \sin}^{ - 1} (0) = 360 \degree \\ \\$
