Answer:
A and D both equations don't have any solution
Step-by-step explanation:
y = 3x + 2
so y ≠ - 3x - 2
if 3x + y = 8
then 3x + y ≠ 9
Minus the 21 from the other side of the equation making it 7x=-21 then u divide the 7 from the x to the -21 resulting in x=-3
Equation is (x+2)^2 - x^2 = 7676
solve the equation by first opening the bracket of (x+2)^2 by A^2 + 2AB +C^2
you'll end up with 4x + 4 = 7672
thus x = 1918 and the next number is 1920.
