Question

using trial and error method solve the following equation​

Answer 1

Answer:

1)

5x-2=18

5x=18+2=20

x=20÷5

x=4

Let's check whether it's correct or not

5×4-2=18

20-2=18

18=18

L.H.S=R.H.S

2)

2m+4=8

2m=8-4=4

m=4÷2

m=2

Let's check whether it's correct or not

2×2+4=8

4+4=8

8=8

L.H.S=R.H.S

3)

y/6=8

y=8×6

y=48

Let's check whether it's correct or not

48/6=8

8=8

L.H.S=R.H.S

4)

x/3-4=5

x/3=5+4=9

x=9×3

x=27

Let's check whether it's correct or not

27/3-4=5

9-4=5

5=5

L.H.S=R.H.S

Hope it helps
