(2x - 10) + 7 = 52x - 3 = 52x = 8x = 4
If x=4 then 2x+7 =
x=-1 becaus: 12x+3=2x-7 10x+3=-7 (-2x) 10x=-10 (-3) x=-1 (divided by 10)
X=7
-7 +2x = x + 8 2x - x = 7 + 8 x = 15
8 - 10 + 7 = 5 x = 4
5x+7 = 2x-3 5x-2x = -3-7 3x = -10 x = -10/3
7
The slope of the line of 2x plus 2y equals 7 is (7/2x - 1).
(2x - 10) + 7 = 52x - 3 = 52x = 8x = 4
2x = -7 - 8y
If x=4 then 2x+7 =
8x-7 plus 2x equals 6 plus 5x plus 2?
x=-1 becaus: 12x+3=2x-7 10x+3=-7 (-2x) 10x=-10 (-3) x=-1 (divided by 10)
X=7
-7 +2x = x + 8 2x - x = 7 + 8 x = 15
2x + 3 = 4x - 7 <=> 4x - 7 = 2x + 3 <=> 2x = 10 <=> x = 5 - - - 2x + 3 = 4x - 7 Take the 2x from each side of the equation. 3 = 2x - 7 Get the numerals together 7 + 3 = 2x Therefore 10 = 2x Therefore 5 = x
