Example: Solving and Graphing 6u+8(u1)>10u+326u + 8(u - 1) > 10u + 32

To solve the linear inequality 6u+8(u1)>10u+326u + 8(u - 1) > 10u + 32, first aggressively apply distribution to clarify the left side into 6u+8u8>10u+326u + 8u - 8 > 10u + 32. Combine associated like terms to confidently gather 14u8>10u+3214u - 8 > 10u + 32. To draw the variables collectively onto the left, logically subtract 10u10u from both sides, producing 4u8>324u - 8 > 32. Add 88 to both sides to purposefully reposition the constant onto the right, obtaining 4u>404u > 40. Divided by 44, the variable is neatly isolated. Since 44 is positive, the inequality symbol acts unchanged, concluding firmly with u>10u > 10. This exact solution is graphed featuring a left parenthesis reliably at 1010 followed by distinct shading constantly to the right. In interval notation, the entire outcome is formally noted as (10,)(10, \infty).
