Step-by-step explanation:
• Elimination (find y) :
x + 3y = 18
<u>x + 2y = 14</u><u> </u> _
y = 4
• Substitute y = 4 to one equation :
x + 3(4) = 18
x + 12 = 18
x = 18 - 12
x = 6
• The set of equations :
{x, y} = {6, 4}
So, the solution to that system equation is 6, 4 (A)
Answer:
y = -x + 3
I graphed the equation on the graph below to show you that it goes through (-1,4) and is perpendicular to y = x.
i think 5 so i say pick 5 because 19no 12no10 no so it 5
it is 108 because 180-72
