4x + 2(3x) = 30
10x = 30
x= 3. Y= 9. (3,9)
Both of them are equations!The solution is (x, y) = (2, 1).
The lines are parallel.
are you talking about a system of equations where x+3y=-7 -x+2y=-8 if so, then the answer is {2,-3}
When x = -2 then y = 4 which is the common point of intersection of the two equations.
x = -1.2, y = -3

x = -1.2, y = -3
x = -2 and y = 4 (-2,4)
Solve this system of equations. 5x+3y+z=-29 x-3y+2z=23 14x-2y+3z=-18 Write the solution as an ordered triple.
first get both your equations into standard form... x + 2y = 9 (equation 1) x + 2y = 13 (equation 2) multiply equation 1 by (-1) -x - 2y = -9 x + 2y = 13 add the equations together 0 + 0 = 4 0 = 4 since the equations dont equal out then these equations do not intersect and are therefore parallel. PARALLEL is your answer
There are two equations in the question, not one. They are the equations of intersected lines, and their point of intersection is their common solution.
y = 0 and x = 8.
If: 3x+2y = 5x+2y = 7 which is the same as 7 = 7 = 7 Then: 3x+2y = 7 and 5x+2y = 7 Subtracting equations: x = 0 Therefore by substitution: x = 0 and y = 3.5
Add the two equations you get 5y = 60 so y = 12 and x = 2
