Answer 1

x = - 43.5

Explanation:

Step 1 : Simplify the given equation.

(8x - 20) - 16 = 10x + 51

8x - 20 - 16 = 10x + 51

8x - 36 = 10x + 51

Step 2 : Add/Subtract the alphabetical terms and numerical terms separately.

8x - 36 = 10x + 51

Step 3 : Add 36 on both sides.

8x = 10x + 51 + 36

8x = 10x + 87

Step 4 : Subtract 10x on both sides.

8x - 10x = 87

- 2x = 87

Step 5 : Divide - 2 on both sides.

x = 87/-2

x = - 87/2 (answer in terms of fraction)

x = - 43.5 (answer in terms of decimal)

Hence,

The value of x is - 43.5
