n = - 7

Step-by-step explanation:

$\frac{2m + 5}{n + p} = 9 \\ \\ plug \: m = 2 \: and \: p = 8 \\ \\ \frac{2 \times 2 + 5}{n + 8} = 9 \\ \\ \frac{4 + 5}{n + 8} = 9 \\ \\ \frac{9}{n + 8} = 9 \\ \\ n + 8 = \frac{9}{9} \\ \\ n + 8 = 1 \\ \\ n = 1 - 8 \\ \\ n = - 7$

7(x-2)=28 Can somebody help me and show the steps?

olya-2409 [2.1K]

Since the 7 is in front of the parentheses you must multiply it by everything inside the parentheses. 7 times X is 7X and 7 times -2 is -14. Then you need to make the X be by itself on one side, to do that you have to add 14 to -14 to make it disappear, and also add 14 to the other side, to 28. Then you divide both sides by 7 to make X be by itself.

7(x-2)=28
7X-14=28
7x=42
X=6
