Solve and check result: 3

3

Transposing 2

3

Let us evaluate both the LHS and RHS for validate the answer

L.H.S = 3

R.H.S = 2

L.H.S. = R.H.S.

It proves that result is correct

Solve and check result: 5

5

Transposing 3

5

2

Dividing both sides by 2

Let us evaluate both the LHS and RHS for validate the answer

L.H.S = 5

R.H.S = 3

L.H.S. = R.H.S.

It proves that result is correct

Solve and check result

5

5

Transposing 3

5

2

Dividing both sides by 2, we obtain

Let us evaluate both the LHS and RHS for validate the answer

L.H.S = 5

R.H.S = 5 + 3

L.H.S. = R.H.S.

It proves that result is correct

Solve and check result:

4

4

Transposing 2

4

2

Dividing both sides by 2, we obtain

z=3/2

Let us evaluate both the LHS and RHS for validate the answer

L.H.S = 4

R.H.S = 6 + 2

L.H.S. = R.H.S.

It proves that result is correct

Solve and check result:

2

2

Transposing

2

3

Dividing both sides by 3, we obtain

Let us evaluate both the LHS and RHS for validate the answer

L.H.S = 2

R.H.S = 14 −

L.H.S. = R.H.S.

It proves that result is correct

Solve and check result:

8

8

8

Transposing 3

8

5

5x=0

x=0

Let us evaluate both the LHS and RHS for validate the answer

L.H.S = 8

R.H.S = 3(

L.H.S. = R.H.S.

It proves that result is correct

Solve and check result:

Multiplying both sides by 5, we obtain

5

5

Transposing 4

5

Let us evaluate both the LHS and RHS for validate the answer

L.H.S =

R.H.S = = 40

L.H.S. = R.H.S.

It proves that result is correct

Solve and check result:

Transposing 7x/15 on LHS and 1 on RHS

Multiplying by 15 on both sides

10x-7x= 30

3x=30

Dividing by 3 on both the sides

x=10

Let us evaluate both the LHS and RHS for validate the answer

L.H.S = =23/3

R.H.S= =23/3

L.H.S. = R.H.S.

It proves that result is correct

Solve and check result

Transposing

3y=21/3

3y=7

Dividing both sides by 3, we obtain

y=7/3

Let us evaluate both the LHS and RHS for validate the answer

L.H.S. = R.H.S.

It proves that result is correct

Solve and check result:

Transposing 3

8/5= 2m

Dividing both sides by 2

m=4/5

Let us evaluate both the LHS and RHS for validate the answer

L.H.S = 3m=12/5

R.H.S = 5m –(8/5)=12/5

L.H.S. = R.H.S.

It proves that result is correct
