Question

multiply : (3x plus 7) (2x-4)​

Answer 1

Answer:

Simplifying

3x + -7 = 2x + 4

Reorder the terms:

-7 + 3x = 2x + 4

Reorder the terms:

-7 + 3x = 4 + 2x

Solving

-7 + 3x = 4 + 2x

Solving for variable 'x'.

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

Add '-2x' to each side of the equation.

-7 + 3x + -2x = 4 + 2x + -2x

Combine like terms: 3x + -2x = 1x

-7 + 1x = 4 + 2x + -2x

Combine like terms: 2x + -2x = 0

-7 + 1x = 4 + 0

-7 + 1x = 4

Add '7' to each side of the equation.

-7 + 7 + 1x = 4 + 7

Combine like terms: -7 + 7 = 0

0 + 1x = 4 + 7

1x = 4 + 7

Combine like terms: 4 + 7 = 11

1x = 11

Divide each side by '1'.

x = 11

Simplifying

x = 11
