I have a discussion due I need at least a few sentences explaining "What would you do first: distribute a coefficient over every

term in parentheses or combine like terms in parentheses? Why?"

Answer:

The first thing you ever do when simplifying an expression is distributing the coefficient. For example the expression 3(5x+6+4x) The first thing we would do is distribute the 3 into each value in the parantheses. It would make sense to add the 4x and 5x, but that goes out of order. This is just the rules when it comes to follwing distributive property in it's simplest form.

How to solve 5+|3k-6|=17
Vika [28.1K]

Answer:

Step-by-step explanation:

First move the numbers from the Left hand side to the right hand side. To do so, as it is an equation i.e. both sides must remain the same, you add or subtract the same numbers on both side.

5 + 13k - 61 = 17

5 - 5 + 13k - 61 + 61 = 17 - 5 + 61

13k = 73

k = 73 / 13

k = 5.62 (approximately)

X+2y=5 and 4x-12y=-20 solve using elimination and substitution
mixer [17]

Answer:

(1,2)

Step-by-step explanation:

Substitution:

x + 2y = 5  Solve for x

x = -2y + 5  Substitute -2y + 5 in for x in the second equation

4x - 12y = -20

4(-2y + 5) - 12y = -20  Distribute the 4

-8y + 20 - 12 y = -20  Combine the y term

-20y + 20 = -20  Subtract 20 from both sides

-20y = -40  Divide both sides by -20

y = 2

Plug y into either of the 2 original equations to get x.

x + 2y = 5

x + 2(2) = 5

x + 4 = 5

x = 1

The answer is (2,1).

Elimination:

x + 2y = 5      4x - 12y = -20.  We want to eliminate with the x or the y.  I am going to eliminate the x's that means that I have to multiply the first equation all the way through by -4

(-4)(x + 2y) = (5) (-4)  That makes the equivalent expression

-4x - 8y = -20  I will add that to 4x - 12y = -20

<u>4x - 12y = -20</u>

0x -20y = -40

-20y = -40

y = 2.  Plug 2 into either the 2 original equation to find x.  This time I will select the second original equation to find x.

4x -12y = -20

4x - 12(2) = -20

4x - 24 = -20

4x = 4

x = 1
