10x=10+5 10x=15 Therefore: 2x=3, having divided both sides of the equation by 5.
-10x = -50 Divide both sides by -10 remembering that a minus divided by a minus the quotient then becomes positive: x = 5 So: -10*5 = -50
If you mean: -10x+4-10x+5 then it is 9-20x when simplified

10x - 5 = 2510x = 30x = 3

10x = 2*5*x
5x + 4 = 10x - 5 10x - 5x = 4 + 5 5x = 9 x = 1.8
Given: x2 + 10x - 16 Let: x2 + 10x - 16 = 0 x2 + 10x - 16 = 0 ∴ x2 + 10x + 25 = 16 + 25 ∴ (x + 5)2 = 41 ∴ x = -5 ± √41 ∴ x2 + 10x - 16 = (x + 5 + √41)(x + 5 - √41)
-10x-6 = -12 -10x = -12+6 -10x = -6 x = 3/5
The GCF of 10x and 45 is 5.
