The rubbish browser used for posting questions on this site has nearly trashed your question so I cannot be 100% sure, but I suggest it is the distributive property of multiplication over addition.
-3x + 6 = -30 -3x = -30 - 63x = 36x = 36/3Therefore, x = 12.
The Abelian property or commutativity.
3x + 6y = 363x - 6y = 0 add both equations6x = 36x = 63x - 6y = 03(6) - 6y = 018 - 6y = 018 = 6y3 = yThe solution point is (6, 3).
3x + y + z = 63x - y + 2z = 9y + z = 3y + z = 3y = 3 - z (substitute 3 - z for y into the first equation of the system)3x + y + z = 63x + (3 - z) + z = 63x + 3 = 63x = 3x = 1 (substitute 3 - z for y and 1 for x into the second equation of the system)3x - y + 2z = 93(1) - (3 - z) + 2z = 93 - 3 + z + 2z = 93z = 9z = 3 (which yields y = 0)y = 3 - z = 3 - 3 = 0So that solution of the system of the equations is x = 1, y = 0, and z = 3.
3X - 36 ?????Or,3X - 3 = 6 ?????I will do both. First, 3X - 363X - 36factor out the 33(X - 12)and by the zero property ruleX = 12=====Now, 3X - 3 = 63X - 3 = 6add 3 to each side3X - 3 + 3 = 6 + 33X = 9divide each sides integer by 3(3/3)X = 9/3X = 3=======I leave the checking to you.
6x + 73 < 3x + 103x + 73 < 103x < -63x < -21The largest whole number that complies is -22.
If you mean: 3x^2 +31x +36 then it is (3x+4)(x+9) when factored
3x+2=2x+8x=63x+2 = 2x + 8; first subtract 2x from both sidesx+2=8; then subtract 2 from both sidesx=6
3x+50=6x+14 50-14=6x-3x 36=3x x=36 / 3 therefore x=12
6x3 - 27x2 + 3x + 36 = 3 (x - 4) (x + 1) (2x - 3)
36
It is called the commutative property, a + b = b + a
