Question

Fraction Help!

Answer 1

(3/4)x + (5/8) = 4x I have to find x and put the answer in fraction form

Answer 2

Anyone? :(

Answer 3

\[\frac{ 3 }{ 4 }x +\frac{ 5 }{ 8 } =4x\]
\[\frac{ 3 }{ 4 }x -4x=\frac{ 5 }{ 8 }\]
\[\frac{ 3 }{ 4 }x-\frac{ 4 }{ 1 }x=\frac{ 5 }{ 8 }\]
\[\frac{ -13 }{ 4 }x=\frac{ 5 }{ 8 }\]
\[x=\frac{ 5 }{ 8 }\times \frac{ -13 }{ 4 }\]

Answer 4

simplify

Answer 5

3/4x + 5/8 = 4x -- subtract 3/4x from both sides
5/8 = 4x - 3/4x
5/8 = 16/4x - 3/4x
5/8 = 13/4x -- divide both sides by 13/4
(5/8) / (13/4) = x
5/8 * 4/13 = x
20/104 which reduces to 5/26

another way...
3/4x + 5/8 = 4x -- multiply everything by common denominator of 8
6x + 5 = 32x
5 = 32x - 6x
5 = 26x
x = 5/26

Answer 6

thanks @texaschic101 I got it right! Any chance you are good with inequalities?
