Answer:
x = 3.33
y = 0.33
Step-by-step explanation:
to evaluate for y in this system of linear equation we would say that let
4x-2y=6 ........................................................... equation 1
2x+y=7 ..............................................................equation 2
from equation 2
2x+y=7 ..............................................................equation 2
y = 7 - 2x........................................... equation 3
substitute for y in equation 1
4x-2y=6 ........................................................... equation 1
4x -2( 7 - 2x) = 6
4x - 14 + 2x = 6
6x = 6 +14
6x = 20
divide both sides by 6
6x/6 = 20/6
x = 3.33
put x into equation 3
y = 7 - 2x........................................... equation 3
y = 7 -2( 3.33)
y = 7 -6.667
y = 0.33
