7/2x+1 + 4/4x+2, x≠-1/2

Mathematics
1 answer:
ivann1987 [24]3 years ago
8 0

Step-by-step explanation:

\frac{7}{2x + 1}  +  \frac{4}{4x + 2}

=\frac{7(4x + 2) + 4(2x + 1)}{(2x + 1)(4x + 2)}

= \frac{28x + 14 + 8x + 4}{(2x + 1)(4x + 2)}

=\frac{36x + 18}{(2x + 1)(4x + 2)}

=\frac{9(4x + 2)}{(2x + 1)(4x + 2)}

=\frac{9}{2x + 1}

2= 0.5x

x= 2/0.5

x= 4 movies

put x= 4 in equation 1 or 2

y= 12+2x----------2

y= 12+2*4

y= 12+8

y= $20
