What is the solution to the system of equations? y = 2x + 4 y = -x + 1

den301095 [7]

Step-by-step explanation:

start by setting each equation to each other

$2x + 4 = - x + 1$

first we are going to subtract 2x from both side of the equation

$4 = - 3x + 1$

now subtract 1 from both sides

$3 = - 3x$

now divide by -3 on both sides
