Answer:

<em><u>B. 2x</u></em>

<u>Skills needed: Systems Evaluation, Addition of Equations</u>

Step-by-step explanation:

1) We have a system of two equations and we are adding them together. We need to solve for the x-value of when they are both added together.

We are adding 3x with -x

2) -x just means -1x

---> This means it is: 3x+-1x

-------> When you are adding a negative, you are subtracting a positive:

3x+-1x=3x-1x=2x

2x is your answer.

X+3y=-5
zmey [24]

Answer:

Tyler's - (-5 - 3y) + (3y) = -5

Han's - (x) + (-5 - x) = -5

Step-by-step explanation:

If we are going to use Tyler's first step then we would use x = - 5 - 3y and substitute it in the original simultaneous equation x + 3y = -5, becoming (-5 - 3y) + (3y) = - 5 giving an exact answer of - 5.

But if we are using Han's first step then we will still substitute into the original simultaneous equation but in 3y. It would become

x + (-5 - x) = - 5 which also gives us an exact answer of -5.

Thus proving that both first steps show the same solution of -5.

Show whether each value in the set {2,3,4} is a solution of the equation x + 2 = 6.
enyata [817]

Answer:

4

Step-by-step explanation:

Plug in each given value into the expression to see if it is true.

Set given: {2 , 3  , 4}

Equation given: x + 2 = 6

First, plug in 2 for x. When x = 2:

x + 2 = 6

(2) + 2 = 6

4 ≠ 6.

Next, plug in 3 for x. When x = 3:

x + 2 = 6

(3) + 2 =6

5 ≠ 6.

Finally, plug in 4 for x. When x = 4:

x + 2 = 6

(4) + 2 = 6

6 = 6 (True).

In the given set, only 4 complete the equation.
