Question 1180168
Solving for Two Variables using Elimination
 8x + 6y = 4
-8x + 5y = 62
----------------addition eliminates x, find y
0 + 11y = 66
y = 66/11
y = 6
:
find x using the 1st equation, replace y with 6
8x + 6(6) = 4
8x + 36 = 4
8x = 4 - 36
x = -32/8
x = -4
:
:
Check in the 2nd equation
-8(-4) + 5(6) = 62
+32 + 30 = 62
