Question 231554
8x - 10y = -24
-8x + 6y = 40
--------------------adding eliminates x, find y
0 - 4y = 16
y = {{{16/(-4)}}}
y = -4
:
Find x using the 1st equation
8x - (-40) = -24
8x + 40 = -24
8x = -24 - 40
8x = -64
x = {{{(-64)/8}}}
x = -8
;
:
Check in the 2nd equation
-8x + 6y = 40 
-8(-8) + 6(-4) = 
64 - 24 = 40
