Write each word statement as an equation. Use \(x\) as the variable. Find all solutions from the set \(\\{2,4,6,8,10\\} .\) See Example 5 One more than twice a number is \(5 .\)

Perform each indicated operation. $$ (9-3)-15 $$

Insert one pair of parentheses so that the left side of each equation is equal to the right side. $$ 10-7-3=6 $$

Perform each indicated operation. $$ \left(-\frac{3}{8}-\frac{2}{3}\right)-\left(-\frac{9}{8}-3\right) $$

Perform each indicated operation. $$ \left(-\frac{1}{2}+0.25\right)-\left(-\frac{3}{4}+0.75\right) $$

Write each word statement in symbols. Fifteen is equal to five plus ten.

Write each statement with the inequality symbol reversed while keeping the same meaning. $$ 2.5 \geq 1.3 $$
