2x-4 plus 3 equals 5x-6?
x=1 2/3 How?: 2x-4+3 = 5x-6 2x-1 = 5x-6 2x-1+1 = 5x-6+1 2x = 5x-5 2x-5x = 5x-5x-5 -3x = -5 -3x/-3 = -5/-3 x = 5/3 x = 1 2/3
What is the answer to 5x divided by 7 minus 6 equals x?
If you mean: 5x/7 -6 = x then x = -21

What is x2 - 5x?
X2 - 5X - 6 = 0 What two factor of - 6 add up to - 5 ?? (X + 1)(X - 6) So, X = - 1 ===
What is the answer to 5x - 2 4x plus 4?
If your equation is 5x-2=4x+4 Then this is how you solve it... 5x-2=4x+4 5x-2+2=4x+4+2 5x=4x+6 5x-4x=4x-4x+6 x=6 Your x=6
What is the answer to 5x plus y21 x6-2y?
If you mean 5x+y = 21 and x = 6-2y then x = 4 and y = 1
2x-4 plus 3 equals 5x-6?
x=1 2/3 How?: 2x-4+3 = 5x-6 2x-1 = 5x-6 2x-1+1 = 5x-6+1 2x = 5x-5 2x-5x = 5x-5x-5 -3x = -5 -3x/-3 = -5/-3 x = 5/3 x = 1 2/3
What is the answer to 5x divided by 7 minus 6 equals x?
If you mean: 5x/7 -6 = x then x = -21
Which is the solution set of 4x2 -5x 6?
y + 5x = 6 if x = {-1, 0, 1}

What is the answer to 5x plus y equals 6 and x plus 2y equals 1?
5x + y = 6 so that y = 6 - 5x Also x +2y = 1 so that x + 2*(6-5x) = 1 or x + 12 - 10x = 1 => 9x = 11 or x = 11/9 and then y = 6 - 5x = 6 - 55/9 = -1/9
Factor the following 5x2 x - 6?
5x2 + x - 6 = (5x + 6)(x - 1) 5x2 - x - 6 = (5x - 6)(x + 1)
What are the possible values for x if x squared plus 5x equals 6?
x2 + 5x =6 x2+5x -6 = 0 (x+6)(x-1) = 0 x+ 6 = 0 x = -6 x-1 = 0 x = 1
-5x-6=?

What is 6 plus 2x equals 5x plus 9?
6 + 2x = 5x + 9 , 6 - 9 = 5x - 2x , -3 = 3x , x = -1
X2 plus 5x plus 3 equals 9?
x2 + 5x + 3 = 9 x2 + 5x - 6 = 0 (x + 6)(x - 1) = 0 x = -6 or x = 1
3x plus 2y equals 20 and 5x-2y equals 1?
3x+2y=20 5x-2y=1 (3x+2y) + (5x-2y)= 20+1 3x+5x= 21....... 8x=21.........x=2 5/8 Subsitute x=3(2 5/8)+ 2y=20........... 7 7/8 +2y=20.........2y= 20- 7 7/8....... y=6 1/16
