Question

Write an equation to show the relationship between a and c when a = b + 9 b = c - 2​

Answer 1

Given:

The equations are:

`a=b+9`

`b=c-2`

To find:

The equation that show the relationship between a and c.

Solution:

We have,

`a=b+9` ...(i)

`b=c-2` ...(ii)

Equation (i) can be rewritten as:

`a-9=b` ...(iii)

From (ii) and (iii), we get

`a-9=c-2`

`a-c=9-2`

`a-c=7`

Therefore, the required equation is
`a-c=7`.
