How do you find the x intercept of 4x-3y=12? Algebra Graphs of Linear Equations and Functions Intercepts by Substitution 1 Answer Deepak G. Aug 31, 2016 #x=3# Explanation: #x#- intercept of the equation #4x-3y=12# can be found by plugging #y=0# So we get #4x-3times0=12# or #4x-0=12# or #4x=12# or #x=12/4# or #x=3# Answer link Related questions What is the x and y Intercepts?
