y = 3x - 4
y = 4 + x
Subtract the second equation from the first:
y - y = 3x - 4 - 4 - x
0 = 2x - 8
2x = 8 so that x = 4
Substitute for x into second equation: y = 4 + 4 = 8
So the solutions is (4, 8).
-7.5?
This is an expression and you do not solve an expression, but you can factor this one.X2 + 3X4X2(1 + 3X2)========
12
the roots are 1, - 1/3, - 3 1/2 and 3 1/2
No. It is a quartic equation. The largest power of x in a quadratic equation must be 2.
20
8x8 = 64 so it is 64 (the y) 3x4 = 12 so it is 12 (the x) 64+12 is 76.
Yes. Before using the polynomial for any productive purpose, it would have to be cleaned up and simplified. In that process, the +3x4 and -3x4 would go away, and the highest-order term remaining would be the 4x3.
3x4-7x3+5x2-3x+6
3x4 plus 5x3 plus x2 - 5 divided by x 2 =[(3x4) + (5x3) + (x2 - 5)]/x2 =(12 + 15 + x2 -5)/x2 =(27 - 5 + x2)/x2 =(22 + x2)/x2
Because 3 x 4 = 12
the answer is 12 3x4 equals to 12
