1.3+2.1 = -2x-2
3.4=-2x-2
5.3=-2x
(multiply both sides by -1)
2x=-5.3
(divide both sides by 2)
x=2.7
Hope that helped!

2x2 - 5x + 6 = ?x = -1(2 x (-1)2) - (5 x -1) + 6 = ?(2 x 1) - (-5) + 6 = ?2 + 5 + 6 = 13
X +13 equals 22, X equals nine
12 + 5 equals...
To solve for x, we'd have to know what this expression equals.
2x2 - 3 = 13 So 2x2 = 16 x2 = 8 So that x = ±2√2
13
If: 2a+13 = 5a+1 Then: a = 4
7+6
Set up the equation and solve: 13 = 7 + s (next subtract 7 from each side of the equation to solve for s) 6 = s
Simply by using the formula x= -b +/- Underroot of (b2 - 4.a.c) / 2.a 2+x-6=2x+4
6+8=14
