this is what you would: 4x+6=3x-1 -6 -6 ---- 4x=3x-7 -3x -3x ---- 1x=-7 ---- x=-7
y= -4x-7 y=3x 3x= -4x-7 3x+4x=7 7x=7 x=1
-1
If you mean: 5x/7 -6 = x then x = -21
3x-8=7x+10x 3x-8=17x -8 = 14x -4=7x -4/7
6 - x + 7 - 3x - 5 = -2x - 10 ∴ x + 3x - 2x = 6 + 7 - 5 + 10 ∴ 2x = 18 ∴ x = 9
3x + 7 = 5x + 13 3x - 5x = 13 - 7 -2x = 6 -x = 3 x = -3
this is what you would: 4x+6=3x-1 -6 -6 ---- 4x=3x-7 -3x -3x ---- 1x=-7 ---- x=-7
3x+7=2x-5 x=-12
7
3x = 18divide both sides by 3x = 6
3x+7=19 3x=12 minus 7 from both sides x=4 divide by three on both sides leaving just what x equals
7-3x = -4x + 13x = 6
• 8-3x+5+5x=7 => -3x+5x=7-8-5 => 2x=-6 => x=-6/2 => x=-3
1. Add 7 to each side: 18 = 3x 2. Divide each side by 3: 6 = x 3. Shout "Eureka".
X=7
y=mx+b y = 3/7x + 6/7 y equals three sevenths x plus six sevenths
