To simplify the expression (-3x - 5x \cdot 12 - 5x - 5x), first calculate (5x \cdot 12), which equals (60x). Then, combine the terms: (-3x - 60x - 5x - 5x) simplifies to (-73x). Therefore, the answer is (-73x).

To simplify the expression (5X - 6) - (3X + 12), first distribute the negative sign: (5X - 6) - 3X - 12. Then combine like terms: 5X - 3X - 6 - 12, which simplifies to 2X - 18. Thus, the final expression is 2X - 18.
5x - 10 = 3x + 2 5x - 3x = 2 + 10 2x = 12 x = 12/2 x = 6
It is: 8-2x
5x-2 = 3x-6 5x = 3x - 6 +2 5x = 3x - 4 5x - 3x = -4 2x = -4 x = -2
-5x + y = -12- 3x + 6y = -12Since both of expressions have a value of -12, their sum is - 24. This is true only whenx = 20/9 and y = -8/9.-5x + y = -12y = 5x - 12- 3x + 6y = -12-3x + 6(5x - 12) = -12-3x + 30x - 72 = -1227x = 60x = 60/27x = 20/9y = 5x - 12y = 5(20/9) - 12y = 100/9 - 12y = (100 - 108)/9y = -8/9
2x = 5x - 12First step is to move all the like terms to one side of the equation2x (-5x) = -12-3x = -12Next, we can divide both sides by -3 to get rid of the -3 on the left side(-3x)/-3 = (-12)/-3x = 4
5x+8x+3x-2x = 14x
5x+2 = 3x-6 5x-3x = -6-2 2x = -8 x = -4
To simplify the expression (-3x - 5x \cdot 12 - 5x - 5x), first calculate (5x \cdot 12), which equals (60x). Then, combine the terms: (-3x - 60x - 5x - 5x) simplifies to (-73x). Therefore, the answer is (-73x).
I assume you have : 5x - 9 = 3x + 11This is a single algebraic expression.Subtract 3x from both sides.5x - 9 - 3x = 3x + 11 - 3x2x - 9 = 11Add 9 to both sides :2x - 9 + 9 = 11 + 92x = 20x = 10

3x+4 = 5x-6 3x-5x = -6-4 -2x = -10 x = 5
To simplify the expression (5X - 6) - (3X + 12), first distribute the negative sign: (5X - 6) - 3X - 12. Then combine like terms: 5X - 3X - 6 - 12, which simplifies to 2X - 18. Thus, the final expression is 2X - 18.
5x - 10 = 3x + 2 5x - 3x = 2 + 10 2x = 12 x = 12/2 x = 6
It is: 8-2x
