To solve this equation, we need to set each factor equal to zero and solve for y.

Setting 14y + 21 equal to zero:
14y + 21 = 0
14y = -21
y = -21/14
y = -1.5

Setting 1.8 - 0.3y equal to zero:
1.8 - 0.3y = 0
-0.3y = -1.8
y = -1.8 / -0.3
y = 6

Therefore, the solutions to the equation are y = -1.5 and y = 6.
