First: x = 16  y 2x + y = 2 Then you take the value of x that you found ( 16 y ) and replace it by x on the second equation: x = 16  y 2(16y) + y = 2 So x = 16  y 32  2y + y = 2 And x = 16  y y = 30 => y = 30 Thus x = 16  30 = 14

This is a simple method of direct subsitution. You could use matrices, but due to its simplicity its not worth the effort.

my bad. the first equation should read x = 16+ y. You can adjust acoordingly however, the rest of the maths are correct. The end result is y = 10, x = 6

hi kaylaaa add both the equations you'll get 3y=18 y=6 and now substitute back value of y in any one of the equation to get the value of x say , i choose 2nd one 2x=26 x=2 y=6 :) the method i choose to solve is called elimination method where you try to reduce one of the variable by multiplying with some no., you can choose substitution and multiplication method also..:)
