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
