You need to organise your question properly. 3x+2y=4 4x + 3y= 7? Is 4 4x = 44x or 4-4x or 4+4x How can there be 2 equal signs in 1 equation?
8x + 12 = 4x - 4 8x - 4x = -4 - 12 4x = -16 x = -4
-8x + 4 = -4x; (-8+4)x = -4; x = 1.
6x+4 = x+12+4x-6 6x-x-4x = 12-6-4 x = 2
4x+9=25 4x=16 x=4
Only if 4 dollars plus 4 dollars equals 8 dollars.And if you had another 4x, you'd have a dozen-x.

8x + 12 = 4x - 4 8x - 4x = -4 - 12 4x = -16 x = -4
If: 3x+5 = 4x+1 Then: x = 4
Parallel, the slope of the second equation is 4
-8x + 4 = -4x; (-8+4)x = -4; x = 1.
-4x + 8 = -4 -4x + 8 - 8 = -4 -8 -4x = -12 -4x/-4 = -12/-4 x = 3
6x+4 = x+12+4x-6 6x-x-4x = 12-6-4 x = 2
4
4x+9=25 4x=16 x=4
5x + (4 - 4x) = 05x + 4 - 4x = 0x + 4 = 0Subtract 4 from each side:x = -4
8x+2y=4x=-y/4+0.5y=-4x+2
