Answer:

$\frac{3}{4}$

Step-by-step explanation:

$\frac{1}{4} +\frac{1}{2}$

Multiply 4 and 2.

4×2=8

Now this is the tricky part,

$\frac{2+4}{8}$

Multiply 1 and 2, and then 4 and 1. These are going to combine to be the numerator.

4+2=6

Simplify:

$\frac{6}{8} =\frac{3}{4}$

1/2(7x-8)+2x =2-(10x+4

geniusboy [140]

<span>1/2(7x-8)+2x =2-(10x+4)
Distribute
(7x-8)/2 + 2x = 2 -10x -4
combine like terms
(7x - 8)/2 + 2x = -10x - 2
Multiply both sides by 2
7x - 8 + 4x = -20x -4
Combine like terms
11x - 8 = -20x - 4
add 8 to both sides
11x = -20x + 4
add 20x to both sides
11x + 20x = 4
combine like terms
31x = 4
divide both sides by 31
x = 4/31 or </span><span>0.129.

Hope this helps :)</span>
