If you mean: 3x-9 = 12 then the value of x is 7
Without an equality sign the given terms can't be considered to be an equation.
-5x + x + 9 = -4x + 12 -4x + 9 = -4x + 12 9 = 12 This equation has no solution.
-12
-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
y -9 = 3(x -4) y = 3x -12+9 y = 3x -3 in slope intercept form
3x - 2 = 9 3x = 9 + 2 = 11 x = 11/3
In this equation, 3x + 9 = 45. To solve for x, you need to subtract 9 from both sides of the equation, which gives you 3x = 36. To find the value of x, you need to divide both sides of the equation by 3, which gives you x = 12. Therefore, the value of x is 12.
Without an equality sign the given expression can't be considered to be an equation.
Without an equality sign the given terms can't be considered to be an equation.
Without an equality sign the given expression is not an equation and so therefore no solution is possible.
To solve the equation (6x - 3x = 9), first simplify the left side: (3x = 9). Then, divide both sides by 3 to isolate (x): (x = 3). Thus, the solution is (x = 3).
The x-intercept is the point where the y-intercept is zero. "3x 5y 9" is not an equation. 3x+5y+9, or 3x-5y+9, are examples of what was meant to be shown.

To determine if (4, -3) is a solution to the system, we need to substitute x = 4 and y = -3 into both equations. For the first equation (3x - 3y = 21): (3(4) - 3(-3) = 12 + 9 = 21) (True) For the second equation (5x + 4y = 24): (5(4) + 4(-3) = 20 - 12 = 8) (False) Since (4, -3) does not satisfy the second equation, it is not a solution to the system.
-5x + x + 9 = -4x + 12 -4x + 9 = -4x + 12 9 = 12 This equation has no solution.
