9514 1404 393

Answer:

  2. correct

  3. addition property of equality

  4. substitution property of equality

Step-by-step explanation:

You're asked for the Reasons, so you need to examine the Statements to see how you get from one line to the next.

The first line of Statement 2 differs from Statement 3 in that m∠GHI has been added to both sides of the equation (ignoring the typo in statement 3). The reason you can add the same thing to both sides of an equation is given by the <em>Addition Property of Equality</em>.

Statement 3 differs from Statement 4 in that one of the m∠GHI has been replaced by m∠JKL. We can do this replacement because those measures are equal to each other. Replacement of equals by equals is allowed by the <em>Substitution Property of Equality</em>.

Solve the equation.<br><br> 2 ( 4z - 1) = 3(z+2)<br><br> Z=
sveta [45]

Answer:

z = \frac{8}{5}

Step-by-step explanation:

Calculate for the value of z :

2(4z - 1) = 3(z + 2)

-Use <u>Distributive Property</u> on both left and right:

2(4z - 1) = 3(z + 2)

8z - 2 = 3z + 6

-Take 3z and subtract 8z :

8z - 3z - 2 = 3z - 3z + 6

5z - 2 = 6

-Add 2 to both sides:

5z - 2 + 2 = 6 + 2

5z = 8

-Take 5z and divide on both sides:

\frac{5z}{5} = \frac{8}{5}

z = \frac{8}{5}

Therefore, the value of z is \frac{8}{5}.
