Answer 2

Answer:

let the number which is to be found be x in each case

a)x+7=15

x=15-7

x=6

b)6×x+10=58

6x+10=58

6x=58-10

6x=48

x=48÷6

x=8

c)Any two consecutive numbers are going to be nn and n+1.n+1. Subtract 11 from 55, and then divide it in half.

n+n+1=5n+n+1=5

(2n+1)−1=5−1⟹(2n+1)−1=5−1

2n2=42⟹2n2=42

n=2 n+1=3n=2 n+1=3
