Question 776115
How do you solve by using elimination with 2x-4y=28  4x=17-5y
=================================================================
we have two equations in two unknowns
==============================================================
2x = 4y+28
divide both sides of = by 2
x = 2y +14
===================================================================
Substitute for x in second equation
===================================================================
4*(2y+14) = 17 -5y
8y +56 = 17 -5y
13y = -39
y = -3
======================
2x -4*(-3) = 28
2x +12 = 28
2x = 16
x = 8
=========================================
x = 8, y = -3
