3x=2x-12x=-12
There's an equals missing...
It is a quadratic equation and its solutions are: x = -3/2 and x = 3
3x+7=2x-5 x=-12
If you mean: 3+2x = 12 and 4y-x = 5 then their values are x = 4.5 and y = 2.375
3x=2x-12x=-12

It is a quadratic equation and its solutions are: x = -3/2 and x = 3
3x+7=2x-5 x=-12
2x-3 = 9 2x = 9+3 2x = 12 x = 6
If you mean: 3+2x = 12 and 4y-x = 5 then their values are x = 4.5 and y = 2.375
4x - 7 = 2x + 5 2x - 7 = 5 2x = 12 x = 6.
It is a simultaneous equation and when solved its solutions are x = 71/26 and y = 50/13
2x to the fourth power minus 162 equals -146
x = 4 and y = 7
The solutions are: x = -2 and y = 4
