Q:
# Find the solution to the system of equations. You can use the interactive graph below to find the solution. { y = x − 4 y = 4 x + 2 ⎩ ⎪ ⎨ ⎪ ⎧ y=x−4 y=4x+2 x = x=x, equals

Accepted Solution

A:

Answer with explanation:The given system of equation are:1---- y= x -42----- y=4 x+2Equation (1) - Equation (2)→0= x -4 - (4 x+2)→0= -3 x -6-----[Adding and subtracting like terms]Adding 3 x on both sides→3 x= -6Dividing by 3 on both sides→x = -2→Substituting the value of x in equation 1, we get y= -2 -4y =-6→Solution set =(x,y)=(-2, -6)Don't used the graph to find the solution.
