9 - 2k - 3 = k Add 2k to both sides: 9 - 3 = k + 2k Combine like terms: 6 = 3k Divide both sides by 3: 2 = k
2k - 1 = 0 Add 1 to both sides: 2k = 1 Divide both sides by two: k = 0.5
2k + 5
k = 14/43
2k - 3k - m + 2m = -k + m
2k + 3 = 11(- 3 from both sides)2k = 8(divide both sides by 2)k = 4
k=4
If by K2 you are not referring to the mountain, the distributive property of multiplication tells us K * 2 = 2 * K.Therefore: K2 + 2K + 4K = 2K + 2K + 4K = 8K
-4. -3k+10=k+2.... First we have to move the K to one side -3k+10=k+2 __________ This will reduce -3k to -2k and k+2 to just 2 K -2k+10=2 Now we have to subtract 10 to both sides as to get k alone. -2k+10=2 ________ Now we should have -2k on one side and 2-10 on the other. -10 -2k=2-10....... 2-10= 8. We have to get -2k into just K on itself so we divide by 2. -2k=-8 ______ Your answer is 4. You have to do one side what you do the other. 2
neg(-k) + neg(-k) = k + k = 2k = 4
2K + Cl2 --> 2KCl
==> 3k+14=k ==>3k-k=-14 ==>2k=-14 ==>k=-7 ans...
3k-1=k+2 2k=3 k=3/2=1.5
Equation: 2kx^2 -2x^2 +2kx +k -1 = 0 Using the discriminant: (2k)^2 -4*(2k -2)*(k -1) = 0 Solving for k in the discriminant: k = 2 + or - square root of 2
