21 - 16.75 is 4.25. Do the problem on a calculator and you'll get it.
Answer: x = -5
Step-by-step explanation:
First convert 3/4 to decimal= 0.75
0.75 (8x - 4) = 7x + 2
6x - 3 = 7x + 2
Transpose 7x from right hand side to the left hand side
6x - 7x = 2 + 3
-x = 5
x = -5
I hope this helps.
28 x 12 = 336
336 - 16 = 320
320 divided by 4 = 80
