Question

solve the following equations 1. y-4=7 2. x-5=0 3. 3(n-2)=48​

Answer 1

Answer:

1)

y-4=7

y=7+4

y=11

Check whether it's correct or not

11-4=7

7=7

L.H.S=R.H.S

hence verified

2)

x-5=0

x=0+5

x=5

check whether it's correct or not

5-5=0

0=0

L.H.S=R.H.S

hence verified

3)

3(n-2)=48

3n-6=48

3n=48+6=54

n=54/3

n=18

check whether it's correct or not

3(18-2)=48

3×16=48

48=48

L.H.S=R.H.S

hence verified

hope it helps
