Find the Product 9x-7i>3(3x-7u)

$9 x - 7 i > 3 (3 x - 7 u)$

Step 1

Simplify $3 (3 x - 7 u)$ .

Rewrite.

$9 x - 7 i > 0 + 0 + 3 (3 x - 7 u)$

Simplify by adding zeros.

$9 x - 7 i > 3 (3 x - 7 u)$

Apply the distributive property.

$9 x - 7 i > 3 (3 x) + 3 (- 7 u)$

Multiply.

Multiply $3$ by $3$ .

$9 x - 7 i > 9 x + 3 (- 7 u)$

Multiply $- 7$ by $3$ .

$9 x - 7 i > 9 x - 21 u$

Step 2

Move all terms containing $x$ to the left side of the inequality.

Subtract $9 x$ from both sides of the inequality.

$9 x - 7 i - 9 x > - 21 u$

Combine the opposite terms in $9 x - 7 i - 9 x$ .

Subtract $9 x$ from $9 x$ .

$0 - 7 i > - 21 u$

Subtract $7 i$ from $0$ .

$- 7 i > - 21 u$

Step 3

The variable $x$ got canceled.
