If you mean: 4x-5y = -12 and -x+5y =18
Then the solutions of the equations are: x = 2 and y = 4

What is 8(4x- 12) =?
8-3x-x = 12 8-4x = 12 -4x = 12-8 -4x = 4 x = -1
Solve 4x equals 72?
4x = 72.divide both sides by 4x = 18
4x plus 6 equals 6x-12?
Given, that 4x + 6 = 6x - 12; then, (6x - 12) - (4x + 6) = 0, 2x - 18 = 0, and 2x = 18. Thus, x = 9. Checking, we substitute 9 for x in the equation: 4(9) + 6= 6(9) - 12; whence, 36 + 6 = 54 - 12, and 42 = 42, which is patently true. What this means is that the original equation is true exactly when x = 9; otherwise, it is false. We call 'x = 9' the solution to the given equation.
What is 4x-1 and then times by 2 equals 18?
2(4x-1)=18 is the question. In this case, x=2.5
What is 8x - 4x 12?
If that's 8x - 4x = 12, it's an equation where x = 3
8x plus 30 equals 4x plus 18 solve for x?
8x+30=4x+18 -4x -4x 4x+30=18 -30 -30 4x=-12 4x/4=-12/4 x=-3
What is 4x plus 12-5x-30?
4x+12-5x-30=-x-18
5x-18 equals 4x plus 7?
5x - 18 = 4x + 7Add 18 to each side:5x = 4x + 25Subtract 4x from each side:x = 25
How do you answer -2x plus 6 less than equal to 4x plus 18?
-2x + 6 <= 4x + 18 -2x <= 4x + 12 -12 <= 6x -2 <= x
What is 18-2x equals 4x-12?
x = 5
Four times a certain number dininished by 12 equals 60 what eqautions will solve the problem?
Let the number be x: 4x-12 = 60 4x = 60+12 4x = 72 x = 18
8x plus 30 equals 4x plus 18?
subtracting gives 4x = -12 so x = -3
Find the value of x: 2(4x + 4) = (4x - 12)?
2(4x + 4) = (4x - 12) 8x + 8 = 4x - 12 8x - 4x + 8 = 4x - 4x - 12 4x + 8 = -12 4x + 8 - 8 = -12 - 8 4x = -20 4x/4 = -20/4 x = -5
-4x is greater than -12?
8
What is 8(4x- 12) =?
8-3x-x = 12 8-4x = 12 -4x = 12-8 -4x = 4 x = -1
What is this equation?
4x + 3 cannot equal 4x + 12:4x + 3 = 4x + 12 (given)3 = 12 (subtract 4x from both sides)
8x plus 12 equals 4x-4?
8x + 12 = 4x - 4 8x - 4x = -4 - 12 4x = -16 x = -4
