answers:
G.K.K say: 3x-4 =7x +12
add -7x to both sides
- 4x -4 = 12
add + 4 to both sides
- 4x = 12 + 4
- 4x = 16
x = -4
-
MICHAEL K say: x = - 4.
-
Krishnamurthy say: x = -4
-
Jason say: 3x = 7x + 16
4x + 16 = 0
4x = -16
x = -4
-
Sophie say: 3x - 4 = 7x + 12
-7x from both sides
-4x - 4 = 12
+ 4 to both sides
-4x = 16
Divide both sides by -4
X = -4

Salt and Peppy say: x = -4
-
Zia say: 3x+4-7x=12
We simplify the equation to the form, which is simple to understand
3x+4-7x=12
We move all terms containing x to the left and all other terms to the right.
+3x-7x=+12-4
We simplify left and right side of the equation.
-4x=+8
We divide both sides of the equation by -4 to get x.
x=-2
