4 * 3=12 * 2-X-3
12=24-(X+3)
0=12-(X+3)
0=X-9
X=-9
43=122-X-3
12=24-(X+3)
0=12-(X+3)
0=X-9
X=-9
4x3= 12x2-x-3
The answers are x= -.4324426. or x= .6157299 or x= 2.816713
These are approximations.
4 x 3 = 12 x 2 - X - 3
12 = 24 - X - 3
12 = 21 - X
X =21 - 12
X = 9

The "degree" is the highest power - in this case, the 3 in 4x3 (4 times to the third power).
x: x2 - 81 = 0
y=±√15

4x3=12x20=240the answer to 4x3xx20 is 240
The "degree" is the highest power - in this case, the 3 in 4x3 (4 times to the third power).
2sinx+1 equals 0
For y - 2y - 3y equals 0, y equals 0.

"x equals 0" is an equality, not an inequality. The question is, therefore, not consistent.
Suppose x3-4x = 0. To solve, factor: x3-4x = x(x2-4) = x(x+2)(x-2) = 0 Now, a product equals 0 if and only one or more of the factors equals 0, so set each factor to 0 and solve. The roots are 0,-2 and +2.
x: x2 - 81 = 0
Solve this problem -x squared -40x- 80 =0
x=2
10x=x 9x=0 x=0
Divide both sides by 8: m = 0
-y + y equals 0.
