Question

The x intercept of line ax + by = c + dx + ey is

Answer 1

`(c)/(a-d)`

Explanation:

Hi there!

Firstly we insert 0 into y functions since at the x intercept, y = 0. Then:

ax + b(0) = c + dx + e(0)

(1) ax = c + dx

Now we bring the x functions to one side:

ax - dx = c

As x is a common factor we factorise the left hand side:

x ( a - d) = c

Now make x the subject:

x =
`(c)/(a-d)`

Hope this helped!
