Question

What is the x-intercept of the equation whose line is 3x + 10y = 36?

Answer 1

For this case we have the following linear equation:

`3x + 10y = 36`
The intersection with the x axis occurs when the value of y is equal to zero.
We then have to replace y = 0 in the equation:

`3x + 10 (0) = 36`
Rewriting:

`3x + 0 = 36 3x = 36`
Clearing x we have:

`x = 36/3 x = 12`
Answer:
The x-intercept of the equation whose line is 3x + 10y = 36 is:
x = 12
