Answer:

2(x + 3) = x - 4 \\ 2x + 6 = x - 4 \\ 2x - x =  - 4 - 6 \\ x =  - 10

___o___o___

4(5x - 2) = 2(9x + 3) \\ 20x - 8 = 18x + 6 \\ 20x - 18x = 6 + 8 \\ 2x = 14 \\  \\ x =  \frac{14}{2}  \\  \\ x = 7

I hope I helped you^_^

Answer:  16) \bold{\sqrt{x}}        (17) \bold{\dfrac{x-4}{2}}        (18) \bold{\sqrt{x}-2}       (19)  3x - 18

<u>Step-by-step explanation:</u>

Inverse is when you swap the x's and y's and then solve for y

16) Given: y = x²

Swapped: x = y²

                \bold{\sqrt{x} =y}

17) Given:  y = 2x + 4

Swapped: x = 2y + 4

            x - 4 = 2y

            \bold{\dfrac{x-4}{2}=y}

18) Given:  y = (x + 2)²

Swapped: x = (y + 2)²

               √x = y + 2

        \bold{\sqrt{x}-2=y}

19) Given:  y=\dfrac{1}{3}x+6

Swapped: x=\dfrac{1}{3}y+6

            x - 6 = \dfrac{1}{3}y

            3(x - 6) = y

            3x - 18 = y

Which number belongs to the solution set of the equation below? x - 7 = 35 A. 22 B. 28 C. 42 D. 41
TiliK225 [7]
Hey there!

To find a solution that would satisfy the value of x, the first thing you must do is to first solve for x. To solve x-7=35, you must add 7 to both sides to isolate x. This should result in x=42.

When you look at the answer choices given, notice that choice C is the solution for x, 42.

Therefore, your answer would be C. 42.

To check if this is correct, you can plug 42 back into the equation x-7=35 to see if you get a true statement:
42-7=35
35=35

Hope this helps!
