Answer 1

Answer:

Step-by-step explanation:

Let the number be x.

According to the question, 8x+4=60

⇒ 8x=60–4 ⇒ 8x=56

⇒ x=568 ⇒ x=7

(b) Let the number be y.

According to the question, y5–4=3

⇒ y5=3+4 ⇒ y5=7

⇒ y=7×5 ⇒ y=35

(c) Let the number be z.

According to the question, 34z+3=21

⇒ 34z=21–3 ⇒ 34z=18 ⇒ 3z=18×4

⇒ 3z=72 ⇒ z=723 ⇒ z=24

(d) Let the number be x.

According to the question, 2x–11=15

⇒ 2x=15+11 ⇒ 2x=26

⇒ x=262 ⇒ x=13

(e) Let the number be m.

According to the question, 50–3m=8

⇒ –3m=8–50 ⇒ –3m=–42

⇒ m=–42–3 ⇒ m=14

(f) Let the number be n.

According to the question, n+195=8

⇒ n+19=8×5 ⇒ n+19=40

⇒ n=40–19 ⇒ n=21
