Answer:

These equations are equivalent because after you solve the equation the answer are the same. For example 2+2 and 3+1 are equivalent. They both equal four. In these problems are x=3 and x=3.5 they are the same beause of the answer on problem 2 6-x. That makes them both have the same answer

Step-by-step explanation:

7x-9=12

+9=+9

7x=21

/7=/7

x=3

Need help with this question <br><br> 2 + (4h- 1) = 13h<br><br> Need All Steps Plz

vredina [299]

Answer and Step-by-step explanation:

For this equation, we are solving for h.

We are given the equation:

2 + 4h - 1 = 13h

<u>First, we need to </u><u><em>Simplify</em></u><u> the equation.</u>

2 - 1 + 4h = 13h

1 + 4h = 13h

<u>Now, we need to </u><u><em>Subtract</em></u><u> 4h from both sides of the equation.</u>

1 + 4h - 4h = 13h - 4h

1 = 9h

<u>Finally, we </u><em><u>Divide</u></em><u> both sides by 9 to get h.</u>

$\frac{1}{9} = h$

<u>h is equal to </u> $\frac{1}{9}$ <u>.</u>

To check your answer, we plug $\frac{1}{9}$ back into the given equation.

$2 + 4(\frac{1}{9} ) - 1 = 13(\frac{1}{9} )\\\\\\\\2 + \frac{4}{9} -1 = \frac{13}{9} \\\\\\1 = \frac{9}{9} \\\\1 = 1$

<u>I hope this helps!</u>
