Question

Solve the following equation....plz show work.
(5x - 1)/2 + (-3x - 1)/4 = 9/2

Answer 1

Best off cross multiplying once again, to be honest.

Answer 2

\[\frac{5x-1}{2}+\frac{-3x-1}{4}=\frac{9}{2}\]
\[\frac{4(5x-1)+2(-3x-1)}{8}=\frac{9}{2}\]

Multiply by 8 both sides and expand the brackets.

Answer 3

20x-4-6x-2=36 I think.
14x-6=36
14x=42
x=42/14
x=3

Answer 4

5x−1/2+−3x−1/4=9/2

4(5x−1)+2(−3x−1)/8=9/2

20x-4-6x-2=64/2
20x-6x=32+4+2
14x=38
x:38/14
x=2.71
