Solve for b. 4b+8geqslant 16 square

To solve the inequality $4b + 8 \geqslant 16$, follow these steps:<br /><br />1. Subtract 8 from both sides of the inequality:<br /> $4b + 8 - 8 \geqslant 16 - 8$<br /> $4b \geqslant 8$<br /><br />2. Divide both sides by 4:<br /> $\frac{4b}{4} \geqslant \frac{8}{4}$<br /> $b \geqslant 2$<br /><br />So, the solution is $b \geqslant 2$.
