+502 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 2nd 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
+9465 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
+2440 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. |
