Solve the inequality 8(u + 8) ≥ 8u+8

Answers

The solution of the given inequality 8(u + 8) ≥ 8u+8 is true for all u.

We have given inequality 8(u + 8) ≥ 8u+8

What is inequality?

A statement of an order relationship greater than, greater than or equal to, less than, or less than or equal to between two numbers or algebraic expressions.

Expand 8(u + 8)

$8u+64\ge \:8u+8$

Subtract 64 from both sides

$8u+64-64\ge \:8u+8-64$

Simplify given term

$8u\ge \:8u-56$

Subtract 8u from both sides

$8u-8u\ge \:8u-56-8u$

Simplify it

$0\ge \:-56$

Therefore the solution is true for all u.
