y+11=-4x 13=y-2x setting them equal

Question

y+11=-4x                                                                                         13=y-2x setting them equal

anonymous · Answer

find the values of y from both the equations and set them equal..hence you get the value of x

anonymous · Answer

could you work it out plz

anonymous · Answer

Since y=-4x-11 and y=2x+13 set -4x-11=2x+13 and solve

anonymous · Answer

both are solved for y so you have two expressions that should be equal bc they both equal y

anonymous · Answer

-4x -11= 2x+13
+4x         +4x  
-11 = 6x + 13
-13         -13
-24=6x

x =  -4
