2y = 4x + 4y = 2x + 2
5+4x-7 = 4x+3-x 4x-2 = 3x+3 4x-3x = 3+2 x = 5
Add 4x - 2 to each side: 5x = 5 x = 1
4x+2<8x+20<4x 0<x x>0
4x+2=2x-102x=-12 x=-6
2*2+4x-9=0 4x=9-4 4x=5 x=5/4
You can't solve it. But you can simplify it to get: 4x+y=2
4x+9 = 7x+3 4x-7x = 3-9 -3x = -6 x = 2
-4x+3 = 23+6x -4x-6x = 23-3 -10x = 20 x = -2
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
5+4x-7=4x+3-1x 4x-2=3x+3 (combined the like terms) +2 +2 (add 2 to both sides) 4x=3x+5 -3x -3x (subtract 3x from both sides) x+5
If you would to solve for (l) then l = 4x/2 + 3/2 (4x + 3 is over 2).To solve for x. x = 2l/4 + 3/4 ( 2l + 3 is over 4)Hope this helps.
