Answer:

Step-by-step explanation:

E is the midpoint of Ac & D is the midpoint of AB

DE = (1/2)BC {Midpoint theorem}

$x +1 = \dfrac{1}{2}(4x - 6)\\\\\\
Multiply \ the \ whole \ equation \ by 2\\\\
2*(x+1) =2*\dfrac{1}{2}*(4x - 6)$

2*x + 2*1 = 4x - 6

2x + 2 = 4x - 6

Add 6 to both sides

2x + 2 + 6 = 4x

2x + 8 = 4x

Subtract 2x from both sides

8 = 4x - 2x

2x = 8

Divide both sides by 2

x = 8/2

x = 4

To find this, we divide 2 over 1/8, to see how many units of 1/8 fits into that of 2.

$\frac{2}{\frac{1}{8} }$ can be rewritten as 2*8. 2*8 = 16 bags.
