(1) 12, (2) 5, (3) 13, (4) 30

Explanation:

(1) Given expression 2x.

Substitute x = 6 in expression 2x.

⇒ 2 × 6 = 12

(2) Given expression 8 + 3 – x

Substitute x = 6 in expression 8 + 3 – x.

⇒ 8 + 3 – 6 = 11 – 6 = 5

(3) Given expression 6 + 7 – 6 + x

Substitute x = 6 in expression 6 + 7 – 6 + x.

⇒ 6 + 7 – 6 + x = 6 + 7 – 6 + 6 = 13

(4) Given expression 5x

Substitute x = 6 in expression 5x.

⇒ 5× 6 = 30
