2x + y = 1 . . . . . (1)
4x + 2y = -2 . . . .(2)
From (1), y = 1 - 2x . . . . . (3)
Putting (3) into (2) gives:
4x + 2(1 - 2x) = -2
4x + 2 - 4x = -2
2 = -2
Therefore, there is no x value as there is no solution for the set of equation.
3x^4y^3 - 15 x^2y^2 +6xy
we can factor out 3xy
3xy(x^3y^2 -5xy+2)
we cannot factor any further
Choice A
100(divided) by x = (The number you would have to figure out.
100/x=...
Did you need the answer or did you need the eqaution
3 + ___ <---- number is ______
