Answer:
(x, y) = (0, -1)
Step-by-step explanation:
The coefficients of x are opposites, so we can eliminate x by adding the two equations.
(6x +y) +(-6x -4y) = (-1) +(4)
-3y = 3 . . . . simplify
y = -1 . . . . . . divide by -3
Now, we need to find x.
6x -1 = -1 . . . substitute for y in the first equation
6x = 0 . . . . . add 1
x = 0 . . . . . . divide by 6
The solution is (x, y) = (0, -1).
Hello!
Let's substitute the values for each ordered pair into the equation and see which one works.
4(3)-1=6+5
12-1=11
11=11
A is a solution
7=14
B is not a solution.
Therefore, a) only (3,2) is a solution to the equation.
I hope this helps!
Answer:
I can not see it well
Step-by-step explanation:
i don't see what your asking but thanxs for the points
i'll give you free point about 40 just look asap because people may snag it
it is 24 because you are adding 18 and 6 the equation is 18 - (-6)
