Question

(4x + 9) by (6x - 7)​

Answer 1

Answer:

Simplifying

4x + 9 = 6x + 7

Reorder the terms:

9 + 4x = 6x + 7

Reorder the terms:

9 + 4x = 7 + 6x

Solving

9 + 4x = 7 + 6x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-6x' to each side of the equation.

9 + 4x + -6x = 7 + 6x + -6x

Combine like terms: 4x + -6x = -2x

9 + -2x = 7 + 6x + -6x

Combine like terms: 6x + -6x = 0

9 + -2x = 7 + 0

9 + -2x = 7

Add '-9' to each side of the equation.

9 + -9 + -2x = 7 + -9

Combine like terms: 9 + -9 = 0

0 + -2x = 7 + -9

-2x = 7 + -9

Combine like terms: 7 + -9 = -2

-2x = -2

Divide each side by '-2'.

x = 1

Simplifying

x = 1

Answer 2

Answer:

12

Step-by-step explanation:

(4x +9) × (6x -7)

4x + 9 × 6x - 7

24x + 2

x = 24 / 2

x = 12
