is (2,3) a solution for both of these equations?
-3x-4y=-18
-2x+4y=8
Let's substitute the values of x=2 and y=3 into the equations to check if they are solutions.
For the first equation, -3x-4y=-18:
-3(2) - 4(3) = -6 - 12 = -18
The left side of the equation equals the right side when x=2 and y=3, so (2,3) is a solution for the first equation.
For the second equation, -2x + 4y = 8:
-2(2) + 4(3) = -4 + 12 = 8
Again, the left side of the equation equals the right side when x=2 and y=3, so (2,3) is a solution for the second equation as well.
In conclusion, (2,3) is a solution for both of these equations.
