Quizplus · Accepted Answer

For the equation $(8y + 21)(5y + 22) = 0$ to be true, either $8y + 21 = 0$ or $5y + 22 = 0$. Solving these gives $y = -\frac{21}{8}$ and $y = -\frac{22}{5}$, respectively.

Solve the Equation (8y+21)(5y+22)=0( 8 y + 21 ) ( 5 y + 22 ) = 0(8y+21)(5y+22)=0

Solve the Equation $( 8 y + 21 ) ( 5 y + 22 ) = 0$
