The answer is A that part is hard in math
Answer:
The subtraction property of equality
Option A is correct
Explanation:
The given equation is:
12 - x = 7x + 32
Subtract 12 from both sides
12 - 12 - x = 7x + 32 - 12
-x = 7x + 20 (Step 1)
From step 1 above, subtract 7x from both sides
-x - 7x = 7x - 7x + 20
-8x = 20 (Step 2)
Since we subtracted 7x from both sides to get step 2, the justification for step 2 is the subtraction property of equality
To prevent any outside forces from intervening.
Answer:
x = 2
Step-by-step explanation:
11+3 = 9x-2x
14 = 7x
x = 14/7
x = 2
