In the first one, IF u solve for x the answer comes to 0.625 or 5/8. So substitute the value of x into the second equation the answer comes to 9.6 or 48/5.

But IF my guess is right so in the first one the equation is \(\frac{1}{x} + 4=8\) and u see that in the 2^{nd} equation its \(\frac{1}{x} +8 \) then the answer should be 16 cuz since +8 is 2 times +4 so then the answer will also be *2.

Hope u got my point.

1/x+4=8, then 1/x+8 equals

1/x + 4 = 8 subtract 4 from both sides

1/x =4 cross multiply

4x = 1 divide both sides by 4

**x = 1/4**

1/x+8 = sub 1/4 for x

1/(1/4) + 8 =

**1 x 4 + 8 =12**

1/x + 4 = 8 Subtract 4 from both sides of the equation.

1/x = 8 - 4

1/x = 4

So.......

1/x + 8 Since 1/x = 4 , we can substitute 4 in for 1/x .

= 4 + 8

= 12

Here's probably the easist method of all!

\(\frac{1}{x}+4=8\) | Add 4 to both sides. |

\(\frac{1}{x}+8=12\) | Done! With only one step, I have shown that \(\frac{1}{x}+8\) is equivalent to 12. |
