x=0 .
−2(8+8x)+7x=−7x+2(x−8)
Step 1: Simplify both sides of the equation.
−2(8+8x)+7x=−7x+2(x−8)
(−2)(8)+(−2)(8x)+7x=−7x+(2)(x)+(2)(−8)(Distribute)
−16+−16x+7x=−7x+2x+−16
(−16x+7x)+(−16)=(−7x+2x)+(−16)(Combine Like Terms)
−9x+−16=−5x+−16
−9x−16=−5x−16
Step 2: Add 5x to both sides.
−9x−16+5x=−5x−16+5x
−4x−16=−16
Step 3: Add 16 to both sides.
−4x−16+16=−16+16
−4x=0
Step 4: Divide both sides by -4.

Answer: Area is 1840units²
Step-by-step explanation:
From the given information,
Firstly, area of a rectangle is given as
A = l × b ie, length multiply by the breadth.
One of the side of the rectangle is known , AD = 16 , now to calculate the other side, we need some calculations.Since FE = 23 and
FD = DE ,,therefore,
DE = 23/2.
From the information, DE = 1/10 of DC. We now find DC the required side for finding the area of the rectangle by simple equation. Since DE = 23/2 , the equation now looks like this to get DC
23/2 = DC/10. Now , solving this
2DC = 23 × 10
2DC = 230
DC = 230/2
= 115.
Now the area of the rectangle will be
A = 16 × 115
= 1840units²
