Mr. Hernando: 4x while the son:x

In 10 years, Mr. Hernando: 4x +10

The solution is 4x + 10 = (x + 10) 2

4x + 10 = 2x + 20

Transpose.

4x - 2x = 20 - 10

2x = 10

Divide both sides by 2 to cancel the two in 2x.

x = 5

Son = 5

Mr. Hernando = 20

Let xbe the son so:

4x-2x=20-10

2x=10

divide both side by 2 to get the answer

x=5

4x-2x=20-10

2x=10

divide both side by 2 to get the answer

x=5
