x times x = x2 (it's like 6 times 6. it would be 62. not 6 times 2. 2x means x times 2)
2x + 6
I assume you wish to simplify the expression (x - 2)/(3x + 9) . (2x + 6)/(2x - 4) = (x - 2)(2x + 6) / [(3x + 9)(2x - 4)] = 2(x - 2)(x + 3) / [6(x + 3)(x - 2)] = 1/3.
2X * 2X * 2X = 8X^3 2X^3 is saying 2*( X * X * X) = 2X^3
2x - 3y = 6 2x = 6 + 3y 2x - 6 = 3y : 3y = 2x - 6 y = 2/3x - 2
Assuming there are no parentheses:2 times X - 1 + 4X - 6 + 2X =2X - 1 + 4X - 6 + 2X =2X + 4X + 2X - 1 - 6 =8X - 1 - 6 =8X - 7
x times x = x2 (it's like 6 times 6. it would be 62. not 6 times 2. 2x means x times 2)
2x - 6
2x - 6
6+2x
-2x-6= -2x-6Another answer:-2x-6 = 2x+6-2x-2x = 6+6-4x = 12x = -3
4
2x - (8 x 6) = 20 2x = 20 + 48 2x = 68 x = 68/2 x = 34
The problem can be written as:2x - 6 = 4and solved as:2x - 6 = 4+6 = +6 [adding 6 to both sides]2x = 10(2x)/2 = (10)/2 [dividing both sides by 2]x = 5
It can be expressed as: 2x-6
2x + 6
if you mean 2x?=6 the answer is 3
