simplify (5-2x)(3)-(3x+2)(-2)

Solution

simplify

(5 - 2 x) (3) - (3 x + 2) (- 2)

Solution

19

Solution steps

(5 - 2 x) (3) - (3 x + 2) (- 2)

(5 - 2 x) (3) = (5 - 2 x) \cdot 3

(3 x + 2) (- 2) = - 2 (3 x + 2)

= (5 - 2 x) \cdot 3 - (- 2 (3 x + 2))

Apply rule:

a - (- b) = a + b

(5 - 2 x) \cdot 3 - (- 2 (3 x + 2)) = (5 - 2 x) \cdot 3 + 2 (3 x + 2)

= (5 - 2 x) \cdot 3 + 2 (3 x + 2)

= 3 (5 - 2 x) + 2 (3 x + 2)

Expand

3 (5 - 2 x) : 15 - 6 x

= 15 - 6 x + 2 (3 x + 2)

Expand

2 (3 x + 2) : 6 x + 4

= 15 - 6 x + 6 x + 4

Add similar elements:

- 6 x + 6 x = 0

= 15 + 4

Add the numbers:

15 + 4 = 19

= 19
