5y-14=11 5y=25 y=5 and to make sure its correct, add the y number (which is 5 in this case) and put it into the equation... 5 x 5 - 14 = 11
y = -1.4
y ∈ ℜ
X=5Y= 92x + 11= ?2(5)+11=?10+11= 21

2x + y = 25 x + y = 14 Subtract second equation from the first: x = 11 Substitute this value of x in the second equation: 11 + y = 14 ie y = 3
-2
y = 1/2
(-2, 11)(-3, 14)(2, -1)
If x=2, then 7x = 14 and if y=5 then 4y=20.
x = 14
2x + y = 3 and y = 5x - 11 1) Plug the second equation for y into the first 2) 2x + (5x - 11) = 3 3) Solve for X 4) 7x = 14 5) x = 2 6) Plug X into either equation to get Y 7) 2(2) + y = 3 8) y = -1

2y - 9x = 14 2y = 14 + 9x y = (14 + 9x) / 2
y = -1.4
5y-14=11 5y=25 y=5 and to make sure its correct, add the y number (which is 5 in this case) and put it into the equation... 5 x 5 - 14 = 11
