Question

José made this table to show the relationship between his age and his cousin Mario's age:
José's age (years)
10 11 12 13
Mario's age (years) 3 4 5 6
José wants an equation he can use to find his own age (j) given Mario's age (m).
Complete José's equation.
j =

Answer 1

Equation j = m + 7 José can use to find his own age.

What are Linear Equation in two variable?

A linear equation in two variable is in the form of ax + by + c = 0; where a, b and c are constant. a or b any one of these must not equal to zero. Here 'x' and 'y' are two variables.

For example:

1. x + 2y = 3

2. 6x + 41y = 4

From the data we can conclude that:

The difference between José's age and Mario's age is 7 years.

Like, when José age was 10 years Mario age was 3 years, here the difference is 7 years.

Also when the José age was 13 years Mario age was 6 years, here also the difference is 7 years.

Now,

when the José age is 'j' then the Mario age must be j - 7:

We have given that Mario age = m

so, m = j - 7

taking 7 to the left side,

j = m + 7

Hence,

Equation j = m + 7 José can use to find his own age.
