How do I solve this algebra equation X+7=2x-8
ale4655 [162]
You know that we have to simplify the algebra equation, so first you have to combine x and 2x. X + 2x equals to 3x. Now that we combined x and 2x which makes 3x, we have to do 7 and -8. 7 + -8 which equals to -1. Therefore, the answer to this algebra equation is 3x + -1.

(6x −9)3−1=((6x−9)3)(0) Solve for X
Tasya [4]

Answer:

Step-by-step explanation:

Remark

Anything multiplied by 0 = 0. So the whole right side is 0.

(6x - 9)*3 - 1  = 0                       Add 1 to both sides.

(6x - 9)*3 - 1 + 1 = 0 + 1             Combine

(6x - 9)*3 = 1                             Divide both sides by 3

(6x - 9)*3/3 = 1/3                      Simplify

(6x - 9) = 1/3                             Remove brackets. Add 9 to both sides

6x - 9+9 = 9 1/3                        Combine

6x = 9 1/3

6x = 28/3                                   Divide both sides by 6

6x / 6 = 28/3 // 6                       Invert the 6 and multiply.

x = 28/3 * 1/6

x = 28/18

Answer

x = 14/9

Solve for x<br><br> 2/7x = 6<br><br> (SHOW YOUR WORK)
castortr0y [4]

Answer:

The answer to your question is  x = 21

Step-by-step explanation:

Equation

                                       \frac{2}{7} x = 6

- Multiply both sides by 7

                                        \frac{(2)(7)x}{7} = 6(7)

- Simplify

                                        2x = 42

- Divide both sides by 2

                                         \frac{2x}{2} = \frac{42}{2}

- Simplify

                                         x = 21
