Answer: f) -7x -9= 12
Step-by-step explanation:
Step 1: Solve the equation. To solve the equation, add 9 to both sides. This is what you would have now. ( -7x = 21 )
Step 2: Now divide -7 from both sides. This is what you would have now.
( x= -3)
Subtract the new value from original value to find the difference:
35 - 28 = 7
Divide the difference by the original amount and multiply by 100:
7/35 = 0.2 x 100 = 20%
The decrease was 20%
