Answer:
3k-2
Step-by-step explanation:
Difference obiously means subtraction in this situation and you are subtraction 2 from the end result. " The product of 3 and k" is just refering to multiplying an unknown value by 3. This unknown value then becomes a variable and 3 becomes the coefficient. When these numbers are put together, they are suggesting multiplication. It can also be written to be less confusing. (3 x k)-2 which is the same thing as 3k-2.
Remember you can do anything to an equation as long as you do it to both sides
2x+3(x-4)=x-20
first distribute
2x+3(x)+3(-4)=x-20
2x+3x-12=x-20
5x-12=x-20
minus x both sides
4x-12=-20
add 12 to both sides
4x=-8
divide both sides by 4
x=-2
Answer:
b-5=16
Step-by-step explanation:
well, it says 5 is LESS THAN b so we do b minus 5 than it says is 16 and is means equal so we do b minus 5 equals 16. super easy once you get the hang of it.

Answer:
(x, y, z) = (1, 2, 3)
Step-by-step explanation:
The equations that result from reduction to row-echelon form are ...
x = 0.4 +0.2t
y = 5.6 -1.2t
z = t
Then t must have a value 5n+3 for 0 ≤ n < 1. That is, t=3.
x = 0.4 +0.2(3) = 1
y = 5.6 -1.2(3) = 2
z = 3
The integers that satisfy are (x, y, z) = (1, 2, 3).
