42 = -7 (z - 3)<br><br> z = ?
liubo4ka [24]

Answer:

The answer to your question is z = -3

Step-by-step explanation:

Expand                 42 = -7(z - 3)

                             42 = -7z + 21

Simplify                 7z = -42 + 21

                             7z = -21

Clear z                    z = \frac{-21}{7}

                              z = -3

lapo4ka [179]

Dividing a whole number and an improper fraction seems tricky, but it just has one or two more steps than the normal process.  First, convert the whole number "9" into a fraction by giving it a denominator of "1".  It should look like 9/1.  Now that both numbers are converted into like formats (improper fractions), you should have 9/1 divided by 5/3.

Second, flip 5/3 over into 3/5 - this is the "reciprocal". Now you have 9/1 divided by 3/5.  It's just a matter of multiplying across the math sentence.  Multiply the numerators (9x3) and the denominators (1 x 5).  Your new fraction should be 27/5.  This is your answer in the improper fraction format.

You can create other formats depending on the expected answer.  For a mixed number, "divide your fraction UP" (27 divided by 5) which gives you 5 and 2/5.  This can be further converted into 5.4 if you need your answer in decimal form.
