4x + y53 is an expression. Thanks to the rubbish browser used by this site for posting question, most mathematical symbols have been stripped out. There is, therefore, no equality not inequality sign and so there is nothing which can be solved.
2y = 4x + 4y = 2x + 2
5+4x-7 = 4x+3-x 4x-2 = 3x+3 4x-3x = 3+2 x = 5
8x+30=4x+18 -4x -4x 4x+30=18 -30 -30 4x=-12 4x/4=-12/4 x=-3
4x+9 = 7x+3 4x-7x = 3-9 -3x = -6 x = 2
-4x+3 = 23+6x -4x-6x = 23-3 -10x = 20 x = -2
3x - 5x + 4x = -2x +4x = 2x
4x + 3y = 8x + y so 3y - y = 8x - 4x ie 2y = 4x so y = 2x
4x-y2=2xy 2x ? y5 if its plus its 7 xy
Add 4x + 2x = 6x + 4 = 6x + 4
Add 4x - 2 to each side: 5x = 5 x = 1
You can't solve it. But you can simplify it to get: 4x+y=2
4x+7-3x = 15 4x-3x = 15-7 x = 8
